Question

Calculate the resistance of a conductor through which a current of 2 A passes, when the potential difference between its ends is 30 V. Therefore, R = \frac{30}{2} = 15 Ω.​

Answer 1

Given,

I=2A

V=30V

By the Ohm's Law Formula V=IR,

30V=2A×R

R=30V/2A

R=15V/A=15 Ω (Volt/Ampere=Ohm)

Answer 2

Answer:

Current through the conductor I = 2 A,

Potential Difference V = 30 V

From Ohm’s Law: R = VI

Therefore, R = 302 = 15
