Q.
In a circuit a cell with internal resistance $r$ is connected to an external resistance $R$. The condition for the maximum current that drawn from the cell is
Current Electricity
Solution:
The maximum current drawn from the cell will be in the case when the external resistance is minimum.
The current in the circuit will be given by:
$I=\frac{E}{R+r}$
So, the smallest value of denominator will give maximum current.
Therefore, for maximum current, the value of $R$ should be equal to zero.
