Cell of operatornameemf E and internal resistance r is connected with resistor of resistance R as shown in the figure. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/a2998de171eafe352e1f73a7bf380987-.png" /> When cell is discharging, then terminal potential difference across the cell is given as V=E-I r where, I= current drawn by cells.

Q. A resistor of resistance ' $R$ ' is connected between the terminals of a cell of emf ' $E$ ' andinternal resistance ' $r$ '. If ' $I$ ' is the current through the circuit. The terminal potential difference of the cell is given by

$I R$

$E - I r$

$\frac{ER}{R + r}$

$\frac{E - R}{r}$

Cell of $emf E$ and internal resistance $r$ is connected with resistor of resistance $R$ as shown in the figure.

When cell is discharging, then terminal potential difference across the cell is given as $V = E - I r$ where, $I =$ current drawn by cells.
