Question

A conductor of 10 Ω is connected across a 6 V ideal source. The power supplied by the source to the conductor is ______.

Options

• 1.8 W

• 2.4 W

• 3.6 W

• 7.2 W

Answer 1

A conductor of 10 Ω is connected across a 6 V ideal source. The power supplied by the source to the conductor is 3.6 W.

Explanation:

Given: V = 6V, R = 10 Ω

Power, P = `V^2/R`

P = `(6)^2/10`

P = 3.6 watt
