A cell of e.m.f. 2V and internal resistance `0.1Omega` is being charged by a current of 5A. Calculate the potential difference between the terminals of the cells.

Text Solution

Verified by Experts

As the battery is being charged,the current goes into the positive terminal as shown in figure.
The potential drop across the intermal resistance is
`5.0Axx0.10(Omega)=0.50V.`
Hence ,the potential dorp across the terminals will be
`2.0V+0.50V=2.5V.`
