Emf of a cell when the cell is charging and discharging and Open circuit and Short circuit
Emf of a cell when the cell is charging and discharging and Open circuit and Short circuit
Open circuit:
- no current is taken from the cell. $i=0$
- The potential difference between A and $\mathrm{B} V_{A B}=E$
- The potential difference between C and $\mathrm{D} V_{C D}=0$
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: $E=V-i R$
