Other methods:
Remove the resistor from the Circuit PCB then test it with a digital multimeter in resistor mode and note down its value. It needs to be separated from board so as to avoid the equivalent resistance from parallel resistors in the circuit.
So, 1 megaohm resistor color code is brown-black-green-gold
Scroll down to jump to SMD LED 5050 and specification in detail.
SMD LED is a Modern era source of light similar to those that is an incandescent lamp and CLF lamps/bulbs. The only difference is shape, size, color, o/p lumens, and power consumption. So let’s discuss more in detail below in this article.
What is SMD LED?
SMD LED stands for Surface Mount Device Light Emitting Diode.
(smd + led)
It is a light-emitting diode in chip shape.
Surface mount devices are the device that can be mounted on PCB’s easily so the SMD led is the LED which can be mounted on PCB or on light strips directly.
SMD are the applications of Surface Mount Technology (SMT), in this Technology electronic components are made such that they can be placed on printed circuit board or any led strip. This makes the device compact and lite in weight. It also called Chip On Board (COB).
Advantage of SMD led over led with pins:
Compact in size
Square or rectangular in shape
Short leads
More efficient
More luminous flux in small dimensions.
Customizable output power
What is the difference between SMD LED and LED?
The SMD led is small-compact & chip diode while LED, in general, is light-emitting diode with long leads. The only thing that makes SMD chip exceptional that, we can place multiple color light diodes in one chip. Thus, we can achieve any resultant color we want (by color mixing theory).
What is better SMD or LED?
Both are of the Same importance. As both SMD and LED are widely used in various engineering fields depending on the requirement and application.
For example, LED is most commonly used in device indicators, and smd led have is general applications in monitor displays, household LAMP & and many more.
Nowadays smd LED is replacing LEDs with pins in every application, this is quit faster and expected to replace up to 80{42041a7992ac3be9e9e29c856254fb498d8c7935d7cf8512da6802e8688e734a} in applications.
Chip led is costlier than normal led due to its technology and other factors.
Numbers and Chips: What does 5630, 3528 and LED 5050 mean?
There is a Standard Size for chip Diodes only. The physical dimension of the smd LED can be determined by seeing at the Number codes on these Chips.
Other than this the output lumens, the power consumption, efficiency, color, number of leads, etc., can learn by referring to the manufacturer’s datasheet provided with that specific chip diode.
The Led-light chips can have different electrical performances despite having the same code number.
For instance, LED 5730 may come with 1W or 3W wattage ratings. Also, the operating voltage can be different from 2.8 volts to 3.4 volts. It anything depending on the technology.
Polarity is generally printed on the chip as + & –
Different technologies provide different luminous flux also consume more power.
Below is the list of some luminous flux (approx values) of different chips per watts:
i) 2835/ 3528 -> 70 lm / W,
ii) SMD LED 5050 -> 80 lm / W,
iii) 5630 -> 80 lm / W,
iv) 5730-05 -> 80 lm / W,
v) 5730-1 -> 100 lm / W
The general formula for size of SMD chips:
BDLN = Breadth (mm) × Length (mm)
= B.D (mm) × L.N (mm)
where, mm is milimeters
eg. the diode chip code3014 will be of dimension 3.0 mm × 1.4 mm.
eg. the diode chip code5050 will be of dimension 5.0 mm × 5.0 mm.

If you are searching for the value of SMD resistor code 151 value then take a look at the image.
Surface-mount resistors, in general, have 3 types of code marks on it.
3-digit-SMD resistor coding system.
4-digit-SMD resistors coding sys,
EIA96-SMD resistor coding sys.
A surface mount device with 151 code shown below with code:
The formulae to calculate the value of SMD resistor code of 3-digit,
Lets the digit on smd be XYZ then,
The left 2 digits in the code showing the significant digits, and the third at the right side is a multiplier digit. This system is same as the resistor color code used in cylindrical carbon type large size. Here, simple decimal numbers are used in lieu of colors.
The value of SMD resistor code 151 is 150 ohms. Check why?
For calculating smd resistor code 151,
Here, X = 1 (1st digit in the code)
Y = 5 (2nd digit)
Z = 1 (3rd multiplier digit)
151 → 15 × 101 Ω
→ 15 × 10 Ω
→ 150 Ω
So, it is a 150 Ω resistor code 151 smd resistor. By scanning these three-digit code you can not infer the power ratings of a resistor so you have to refer the datasheet by the part supplier. The surface mount device size depends primarily on the specified power ratings.
500 ohm resistor color code is not available because the 500 ohm resistor is anonstandard value of resistor:
You do not need to worry about it, just use 510 ohm resistor instead. Because the nearest standard value(to the 500-ohm resistor) is 510 Ohm.
The error percentis only2%, therefore, you can substitute 500 ohm with 510 ohm resistor and circuit performance will nearly remain same.
The alternative method is to connect two 1000 ohm resistor in parallel ie., 1 kΩ || 1 kΩ = 500 Ω
You have to make sure that the resistor you use while using any type of combination should be a precision resistors or it can of 5% tolerance level.
510 ohm instead of 500 Ohm Resistor color code:
{Green, Brown , Brown, Gold]

3rd Brown

4th Gold

1st digit 5
2nd digit 1
3rd multiplier 10
510 Ohms
tolerance
+- 5%
It is calculated as:
1st band= Green= 5(1st digit)
2nd band= Brown= 1(2nd digit)
3rd band= Brown= 10(multiplier)
4th band= Gold= ±5% (tolerance)
Therefore, 51×10±5% ==> 510Ω ==> 0.51kΩ
And tolerance considered as ==> 5% of 510 ==>22.5 Ω
Final practical value of 510Ω resistor lies between 487.5 to 532.5 Ω
With these above two methods, you can get 500 Ohm Resistor replacement for your circuit.
{Bonus tip: You can order for customized resistors which can have nonstandard values, for manufacturing but in large scale, few manufacturing companies do so. This means that you can buy 500 ohm resistor though some customized component seller}

For calculating smd resistor code 104,
Here, X = 1 (1st digit in the code)
Y = 0 (2nd digit)
Z = 4 (3rd multiplier digit)
104 → 10 × 104 Ω

The first 2 digit in the code specifies the significant digits, and the third one is a multiplier digit. This system is same as that of the resistor colour code used in cylindrical carbon resistor large size we use. Here simply numbers are used instead of colors.
For calculating smd resistor code 100,
Here, X = 1 (1st digit in the code)
Y = 0 (2nd digit)
Z = 0 (3rd multiplier digit in the code)
100 → 10 × 100 Ω

Here, X = 1 (1st digit)
Y = 0 (2nd digit)
Z = 1 (3rd multiplier digit)
101 → 10 × 10Ω
→ 10 × 101 Ω
→ 100Ω
So, it is a 100Ω resistor code 101 smd resistor. By looking at this three-digit code you can not guess the power ratings of a resistor so you have to refer the datasheet by the part manufacturer/ supplier. The SMD device size depends primarily on the specified power rating we will be discussing it in next post.
If you are looking for the value in ohm of smd resistor code 103 then you should refer images along with its notations below.

Load resistor is an output testing device or component which is used as ideal output while designing or testing the electrical circuit.
To figure out what is a load resistor in detail you should know about the term load, where it came from? what is its practical use? Various other forms of it in detail below.
What isa load?
The load is any device that can dissipate a considerable amount of power from the source to give the required output.
So this load can be resistive, capacitive, inductive load or combination of any two.
And the power consumed by them can be in the range of a fraction of Watts to several kiloWatts (uW to kW). The term load is broad in nature so we will try to cover that too in further discussion.
The name load is because it is seen as an added load to the circuit, moreover its characteristic is Load impedance.
Characteristics of the load:
a) It can be passive or active in nature.
b) It can be linear or nonlinear in nature.
There are three basic types of load impedance (Z):
The load in the circuit which is resistive in nature is called a resistive load or load resistor. The property of a material or a device to resist the flow of electrons through it is called resistivity.
The resistive loads exhibit the property of pure resistivity (there is no reactance or admittance which are the property of capacitor and inductor, XR ≠ 0, XC = 0 and XL = 0 which implies Z = XR )
Load resistor symbol:
Load resistor formula:
There is no such particular formula, but if you want to find it then refer to the output resistance of amplifier (in the case of the amplifier only)
Furthermore, the load resistor is temporary and a mocked output device for designing and testing purposes only.
You will find this ‘TERM‘ in educational curriculum and tutorials but never in real life practical circuits.
In other words, it is simply a resistor that’s been used as a load in various circuits especially which are under test or for experimental purposes.
Additionally, in practical circuits, there is nothing like a load resistor. This is because output devices with a specific name is used everywhere instead of it.
Example of load resistor:
This can be seen as a speaker is used as an output device in an amplifier circuit in the place of load resistor (RL).
Besides this LED/ lamp/ light bulbs is used as an indicator in the power converter circuits as an output device instead of (RL).
Note that the load resistor value can be anything that can handle the output power from the source circuit.
What is a load resistor in circuit?
Below are those things that can be load resistance:
1) Simple resistor
2) Audio speakers
3) LED lights
4) All types of the light indicator
5) Resistive sensors
6) Buzzers
7) The output stage of the radio frequency amplifier or audio frequency amplifier.
8) Antennas
9) High wattage resistor
It also recognized as a discharge load resistor, this type of device has its application in discharging the stored energy in the output capacitor to avoid electric shock or damage of output devices.
USB mini discharge load resistor is commercially available for sale online. Its objective is to discharge USB source circuits so as to avoid accidental electric shock.
Variable Load resistor:
As the name suggests, variable + load + resistor. It is the load that is having variable resistance that can be controlled either manually or by some other means. This image showing a variable load resistor available for the experimental purpose in labs. It comes with various wattage ratings from 5 Watts to 100 Watts and so on. It is also called as a potentiometer.
Generally, a variable load resistor is used to test the effect of Load resistance on the power consumed by the circuit and several other parameters.
ii) Capacitive load:
The load in the circuit which is capacitive in nature can be termed as capacitive load.
The capacitive load can be the combination of capacitor and inductor in which capacitance should be greater than that of inductance (XC > XL). Or the circuit must contain the capacitor only.
iii) Inductive load:
The load connected in the circuit which is inductive can be termed as inductive load.
The inductive load can be the combination of an inductor and capacitor in which inductance should be greater than that of the capacitor (XL > XC). Or the circuit must be purely made of inductors.
FAQ:
What if we don’t use load resistance?
In such case we can not understand the nature of circuit when used load connected and thus circuit analysis is affected.
What if we use a very small load in the power/electrical circuit?
The circuit will deliver a large current and may cause a short circuit which in results can destroy the driver circuit.
You do not need to worry about it, just use 510 ohm resistor instead. Because the nearest standard value (to the 500-ohm resistor) is 510 Ohm. 
Additionally, in practical circuits, there is nothing like a load resistor. This is because output devices with a specific name is used everywhere instead of it.
