Question

an electric cell does 5J of work in carrying 10 C charge around the closed circuit the emf of cell is

Answer 1

hope this helps........

Answer 2

The emf of the cell is 0.5 volts.

Explanation:

It is given that,

Work done by the electric cell, W = 5 J

Charge, q = 10 C

To find,

The emf of the cell.

Solution,

The emf of a cell is also called its potential difference. It is defined as the work done per unit charge. It is given by :

$U=\dfrac{W}{q}$

$U=\dfrac{5\ J}{10\ C}$

U = 0.5 volts

So, the emf of the cell is 0.5 volts.
