Question

The value of emf of a cell in a closed circuit will be less than the terminal potential difference across the cell when the current in the cell is-

• A. from positive terminal to negative terminal
• B. from negative terminal to positive terminal
• C. zero
• D. infinite

Answer 1

The correct option is B from negative terminal to positive terminal

$\begin{array}{c}{V}_A+V-iR=V_B\\ V_B-V_A=V-iR\end{array}$

$\therefore$ from negative is positive.

$\therefore$ Option $B$ is correct.
