10 ohm Resistor Color Code- Overview and tips
4-bands 10 ohm Resistor color code image is as follows:
10 ohm Resistor color code:
Brown, Black, Black, Gold
| Band | Color | Value |
|---|---|---|
| 1st Brown |  | 1 |
| 2nd Black |  | 0 |
| 3rd Black | | 1 |
| 4th gold |  | +-5% |
| 1st digit 1 2nd digit 0 3rd multiplier:1 0.1 | 10 Ohm tolerance: +-5% |
It is calculated as:
1st band= Brown= 1(1st digit)
2nd band= Black= 0(2nd digit)
3rd band= Black= 1(multiplier)
4th band= Gold= ±5%(tolerance)
Therefore, 10×1±5% ==> 10Ω ==> 10Ω
And tolerance considered as ==> 5%of10 ==>0.5Ω
Final assumed value of 10Ω resistor is between 9.5 to 10.5Ω
Caution:
If resistor contains Red and Brown color bands then check it properly, as red and brown close enough to be very similar when it is already placed in the circuit.
Other methods:
Use DMM to read the value of a resistor. This is the best method. But DMM (digital multimeter) reads the wrong values when a resistor is on board, in such case color code is useful.
Table to obtain 10 ohm resistor when not available:
