Vedclass · Answer

(D) In the given circuit,the terminals $A$ and $B$ are open-circuited.Since no current flows through the circuit $(I = 0)$,there is no voltage drop across any internal resistance of the cell (assuming an ideal cell or negligible internal resistance).Therefore,the potential difference across the open terminals $A$ and $B$ is equal to the electromotive force $(EMF)$ of the cell.Thus,the potential difference is $20 \ V$.

In the shown circuit,what is the potential difference across $A$ and $B$ (in $V$)?
