Question

Explain the conditions for maximum current.

✓

Answer

$1.$ Current in a circuit is given by, $l=\frac{E}{R+r}$
$2.$ Maximum current can be drawn from the emf device, only when $R = 0$, i.e.
$I_{\max }=\frac{E}{R}$
$3. \ I_{max}$ is the maximum allowed current from an emf device $($or a cell$)$ which decides the maximum current rating of a cell or a battery.
