The power consumed by the 4 V battery is, 4 W, 8 W, 7 W, cannot be calculated

Current in the circuit, I = E n e t R n e t ⇒ I = 10 - 4 6 = 1 A ∴ Power consumed by battery P = V × I ⇒ P = 1 × 4 = 4 W

The correct answer is:

4 W

Current in the circuit,

I = \frac{E_{n e t}}{R_{n e t}}

\Rightarrow I = \frac{10 - 4}{6} = 1 A

∴

Power consumed by battery

P = V \times I

\Rightarrow P = 1 \times 4 = 4 W
