Question

What are the advantages of using electrostatic potential?

✓

Answer

The electrostatic potential at each point in space in the vicinity of the source charges represents a scalar field.
The advantages of electrostatic potential field associated with a given distribution of charges are as follows:
- If we know the potential difference between any two points, we can easily obtain the change in potential energy and the work done when a charge placed in the field moves between these two points.
- Electric field is a vector field. Electrostatic potential being a scalar field, the potential at any point due to several charges is simply the algebraic sum of the potentials due to the individual charges.
- The construction of equipotential surfaces helps to visualize the electric field pattern.
- It is possible to calculate the electric field $\vec{E}$ from the scalar potential field function $V$ (by differentiating $V$ with respect to the space coordinates.)
