Question

Electric potential is expressed as a) W x q (b) W/q (c) q/W (d) (W x I)/t

Answer 1

Answer:

The correct Answer is Option no. (B)

Answer 2

Electric Potential is expressed as W/q (option b)

Electric Potential difference is often defined as the work done to transport a unit positive from one place to another in a uniform electric field.

Mathematically we can say :

$\Delta V = \dfrac{work}{charge}$

$\implies \: \Delta V = \dfrac{W}{q}$

Now, when the first point is considered infinity, the potential at infinity is zero, so we can say:

$\implies \: V - V1= \dfrac{W}{q}$

• Here V1 will be zero.

$\implies \: V - 0= \dfrac{W}{q}$

$\implies \: V = \dfrac{W}{q}$

So, option b) is correct ✔️
