100k ohm resistor color code- 4 band
100k ohm resistor color code with 5{42041a7992ac3be9e9e29c856254fb498d8c7935d7cf8512da6802e8688e734a} tolerance is as shown below:
You can calculate the resistance of any resistor using this online 4 Band Resistor Color Code Calculator Tool
100k ohm resistor color code:
Brown, Black, Yellow, Gold
| Band | Color | Value |
|---|---|---|
| 1st Brown |  | 1 (1st digit) |
| 2nd Black |  | 0 (2nd digit) |
| 3rd Yellow |  | 10000 multiplier |
| 4th Gold |  | 5% tolerence |
| practical value can be found using a multi-meter | 100K±5% ohms is its theoretical value. |
Actual value of 100k Ohm resistor is calculated as:
1st band= Brown= 1 (1st digit)
2nd band= Black= 0 (2nd digit)
3rd band= Yellow= 4(multiplier)= 10000
4th band= Gold= ±5{42041a7992ac3be9e9e29c856254fb498d8c7935d7cf8512da6802e8688e734a} (tolerance)
Therefore, 10×1000000±5{42041a7992ac3be9e9e29c856254fb498d8c7935d7cf8512da6802e8688e734a} ==> 1000000Ω ==> 100KΩ
And tolerance considered as ==> 5{42041a7992ac3be9e9e29c856254fb498d8c7935d7cf8512da6802e8688e734a} of 100K ==>5000Ω
Final assumed value of 100KΩ resistor is between 95 kΩ to 105 kΩ
Other methods:
First remove the resistor from PCB then test it with a digital multi-meter in resistance mode and note down its value. It needs to be separated from PCB so as to avoid the equivalent parallel resistance from around resistors in the circuit.
So, 100 Kilo-Ohm resistor color code is brown-black-yellow-gold
Also, check 1mega ohm/ 1M ohm resistor color code
