Under what condition, the current drawn from the cell is maximum?

The maximum current can be drawn from a cell if the external resistance R = 0.

When current is to be drawn at max then the conducting wire rating comes high such that resistance is less.

Resistance R=rho x l/a

Rho = resistivity constant


a=area of cross-section

Hence, if the area of cross-section increases resistance decreases by increasing the rate of current to flow.
