For charging V = E + Ir =2+5 × 0.1 =2.5 V

Q. A battery of e.m.f. $2$ volts and internal resistance $0.1 Ω$ is being charged with a current of $5 A$ . Calculate the potential difference between the terminals of the battery.

1.5 V

2.5 V

1 V

2 V

For charging
$V = E + I r = 2 + 5 \times 0.1$
$= 2.5 V$
