Question

What p.d. is needed to send a current of 6 A through an electrical appliance having a resistance of 40 Ω?

Answer 1

We know that V = IR

Here, I = 6 A

R = 40 Ω

So, V = 6 x 40

V = 240 V

So 240 V is the potential difference needed to send a current of 6 A through an electrical appliance that has a resistance of 40 Ω.
