Current in the circuit, I=(En e t/Rn e t) ⇒ I=(10 - 4/6)=1A ∴ Power consumed by battery P=V× I ⇒ P=1× 4=4 W

Q. The power consumed by the $4 V$ battery is

$4 W$

$8 W$

$7 W$

cannot be calculated

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
$P = V \times I$
$\Rightarrow P = 1 \times 4 = 4 W$

Q. The power consumed by the 4V battery is

4W

8W

7W
