Question

The terminal potential difference of a cell when short-circuited is ($E=EMF$ of the cell)

• A. $E$
• B. $E/2$
• C. Zero
• D. $E/3$

Answer 1

The correct option is C Zero

When a cell is short circuited it gives a sense that the current in the circuit is equal to zero and as you notice in the above equations that in both cases if the current is equal to zero then the terminal potential is equal to the potential of the cell or the EMF of the cell.

Hence, in short circuiting

$I=0$, so $V=0$
