Question

Second band represents which value of resistance in a 4-band resistor?

First digit
Second digit
Multiplier
Tolerance

hint Hint:

Second band represents the second digit value of a resistance in a 4-band resistor.

The correct answer is: Second 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.
