Question

(5) If the potential difference across a wire is 2 V
and the current through the wire is 1 A, the
electric power
(a) 4 W
(b) 1/2 W
(c) 2 W
(d) 1/4 W​

Answer 1

Answer:

2W

Explanation:

power= VI

power=2×1

power =2W

Answer 2

Answer:

Option C

2W

Explanation:

Given:-

the potential difference across a wire is 2 V

the potential difference across a wire is 2 Vand the current through the wire is 1 A,

To find:-

the electric power

electric power Solution:

The potential difference across the wire=2V

The Current through the wire=1A

We know that:

Power=voltage × current.

Power(P)=2V×1A

Power(P) = 2W

Answer:-

electric power = 2W
