Question
What is the tolerance that needs to be added if the last band is of red color?
- ± 0.05%
- ± 10%
- ± 2%
- ±1%
Hint:
The tolerance that needs to be added if the last band is of red color is ± 2%
The correct answer is: ± 2%
- A resistor is an electrical component with two terminals which implements electrical resistance in a circuit.
- The colour codes are used as a symbol to specify the reliability and tolerance of a resistor.
- Tolerance can be described as the variation between the resistance of the resistor and the actual resistance.
- Each colour band describe individual tolerance values.
