Question

The potential difference across a circuit in which a bulb of 100 W is connected and a current of
7A is flowing?

Answer 1

Explanation:

using power equation

P = V x I

100 / 7 = 14.3 V

Answer 2

Answer:

Since P = VI

So V = P/I

Here , P= 100 w and I = 7 A

Therefore V = 100w/7A = 14.28v ( approx)
