About 2021 Resistor Color Code Calculator
Color code
The color codes on a resistor identifies the resistance, and the tolerance of a resistor. This app help calculate Resistors with 4 and 5 colors bands as well as their tolerance. In the following, the meaning of each band is described for each type of resistor.
4-band resistor
1. The first band represents the first digit of the resistance value.
2. The second band represents the second digit of the resistance value.
3. The third band represents the multiplication factor of the resistance value.
4. The fourth band represents the tolerance in percentage of the resistance value.
5-band resistor
1. The first band represents the first digit of the resistance value.
2. The second band represents the second digit of the resistance value.
3. The third band represents the third digit of the resistance value.
4. The fourth band represents the multiplication factor of the resistance value.
5. The fifth band represents the tolerance in percentage of the resistance value.
