What will be the resistance (in ohms) of a resistor, when the current through the resistor is 2 A and the potential difference between the ends of the resistor is 40 V? Correct Answer 20

Given that, current (I) = 2 A

Potential difference (V) = 40 V

According to Ohm’s law, V = IR

⇒ 40 = 2 × R ⇒ R = 20 Ω
