State whether the electric potential is a scalar or a vector quantity.

Open in App

Solution

Electric potential is defined as the amount of work done to move a unit positive charge from infinity to that point.
$e l e c t r i c p o t e n t i a l = \frac{w o r k d o n e}{c h a r g e}$
$1 V = \frac{1 j o u l e}{1 c o u l o m b}$
Since work done is a scalar quantity and charge is also a scalar quantity. Hence, an electric potential is a scalar quantity.
