150 Ohm Resistor color code- Overview
The 150 ohm Resistor color code for 4-band resistor is as shown in the image below:
[Brown, Green, Brown, Gold]
| Band | Color | Value |
|---|---|---|
| 1st Brown |  | 1 |
| 2nd Green |  | 5 |
| 3rd Brown | | 10 |
| 4th gold |  | 5% |
| 150±5% Ω |
150 ohm resistor color code for 4-band is calculated as:
- (1st digit) = Brown = 1
- (2nd digit) = Green = 5
- (multiplier) = Brown = 1 = 10^1 = 10
- (tolerance) = Gold= ±5%
∴ 15×10±5% –> 150 ohms –> 150 Ω
∴ the real value of 150 Ω resistor is between 142.5 Ω to 157.5 Ω
Description: From the resistor color code table we have to find the color code of resistor according to its decimal value of each band counted from left to right.
Thus, for 120 ohm resistor, 1st digit is ‘ 1 ‘, ∴ look for color in a chart with value 1, then it’s your 1st color(say brown).
The 2nd digit is ‘ 3 ‘, ∴ look for color in a chart with value 2, then it’s your 2nd color (say green).
The 3rd digit ‘1’ (but value 10^1 = 10) is multiplier ‘ 10 ‘, ∴ look for color in table with value 1, then it’s your 3rd color band (say brown).
- The last bands in 4th and 5 th bands resistors gives the tolerance value of the resistor. In that, the Gold band indicates a 5% tolerance of the resistor value. For Silver band, it is 10%, and Brown its value points at 1% tolerance. If the 4th color band is absent then it is assumed to be 20% tolerance.
