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