Why do electricians wear rubber hand gloves while working with electricity? b) What potential difference is needed to send a current of 6A through an electrical appliance having a resistance of 40Ω?

1. We know that rubber is a good insulator or a bad conductor of This is the reason why electricians wear rubber hand gloves while working with electricity.

1. Given, Current, I = 6A

Resistance, R = 40Ω We know that,

V = IR

V = 6 × 40 = 240V
