Question

A current of 5 A flows through a conductor having resistance 2 Ω. The potential difference (in volt) across the ends of the conductor is:

A.

3

B.

7

C.

2.5

D.

10

Correct option is D

Given:

I = 5A (Current)

R= 2Ω (Resistance)

Solution:

To find the Potential Difference (V) accross end of the conductor use ohm's law.

V = I × R

Substitute the value

V = 5 × 2 = 10 A

Thus the correct answer is (D)
