Question

how the maximum current can be drawn from the cell.

Answer 1

When is cell is short , then the terminal potential reduces to zero and then a maximum current is drawn from the cell.

So to draw Maximum current from the cell we have to short the cell.

Answer 2

Its quite simple how to draw maximum current from the cell if we shorted it..

Let me explain through equation

Now, you know

V cell = I R

Where.

V cell = E−Ir

So, for a given cell, lets assumed V to be constant. In that case, current I is inversely proportional to load resistance R. And since the lowest, real value of R is zero,

maximum current would be drawn when the cell is shorted across its terminals.

I = V cell / R

According to this equation, for R= 0 you will get maximum current..
