Emf of a cell when the cell is charging and discharging and Open circuit and Short circuit

Open circuit t:

- no current is taken from the cell. $i = 0$
- The potential difference between A and $B V_{A B} = E$
- The potential difference between C and $D V_{C D} = 0$

Short circuit

Two terminals of a cell are joined together by a thick conducting wire
- Maximum current $i = \frac{E}{r}$
- $V = 0$

Equation of cell
1. When supplying the current: $E = V + i R$
2. When the cell is being charged: $E = V - i R$
