Question

A Carbon resistor has three strips of red colour and a gold strip. What is the value of

resistor? What is tolerance?​

Answer 1

AnswEr :

It is given that a carbon resistor has 3 strips of red colour and 1 strip of gold colour.

So,

By using the colour code,

Value of resistance :

$\implies$ 22 × 10²

$\implies$ 5% ohm

Therefore, gold has 5% tolerance.
