What will be the value of current (in A) through a resistor, when the power dissipated through the resistor is 40 W and the potential difference between the ends of the resistor is 100 V?

What will be the value of current (in A) through a resistor, when the power dissipated through the resistor is 40 W and the potential difference between the ends of the resistor is 100 V? Correct Answer 0.4

Given that, Power (P) = 40 W

Potential difference (V) = 100 V

We know that, P = VI

⇒ 40 = 100 × I ⇒ I = 0.4 A
