Question

What is the meaning of ± in front of the tolerance percent?

Percentage of accuracy between the indicated value and the actual value.
Percentage of error in resistor's resistance.
Both a and b
None of the above.

hint Hint:

It means percentage of accuracy between the indicated value and the actual value and percentage of error in resistor's resistance.

The correct answer is: Both a and b

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.

Low tolerance means low variation.

± means percentage of accuracy between the indicated value and the actual value and percentage of error in resistor's resistance.
