Question
First band represents which value of a resistance in a 4-band resistor?
- First digit
- Second digit
- Multiplier
- Tolerance
Hint:
First two bands indicate the significant digits in 4 band resistor
The correct answer is: First digit
- 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.
- The colour codes are used instead of values because of convenience.
- There are different types of resistors like 4 band, 5 band and 6 band resistors.
- These bands describe individual values.
- So in 4 band resistor first digit is represented by First Band
