Question

If ‘V’ denotes electric potential, ‘W’ the energy spent in bringing a Q units positive charge from infinity to a given point in an electric field then:

Options

• $$V = \frac{W}{Q}$$

• $$V = \frac{Q}{W}$$

• $$V = Q \times W$$

• $$V = Q + W$$

Answer 1

$$V = \frac{W}{Q}$$

Explanation:

Electric potential is the work done per unit charge.

So `V = W/Q`

The other three expressions do not give electric potential.
