## What is the formula of potential electric potential?

A spherical sphere of charge creates an external field just like a point charge, for example. The equation for the electric potential due to a point charge is **V=kQr V = kQ r** , where k is a constant equal to 9.0×10^{9} N⋅m^{2}/C^{2}.

## What is electric potential answer?

Electric potential is **the amount of potential energy per unit of charge**. … When work is done on a positive test charge to move it from one location to another, potential energy increases and electric potential increases.

## What is electric potential called?

Electric potential difference, also known as **voltage**, is the external work needed to bring a charge from one location to another location in an electric field.

## Why is electric potential important?

The discussion of electric potential is important because **we are always looking for convenient sources of energy**. Since any two point charges exert a force of attraction or repulsion on each other, if one charge moves in the field of the other a distance dr under an average force F, the work done is equal to Fdr.

## Is electric potential positive or negative?

Note that the electrical potential energy is **positive if the two charges** are of the same type, either positive or negative, and negative if the two charges are of opposite types. This makes sense if you think of the change in the potential energy ΔU as you bring the two charges closer or move them farther apart.

## Why is electric potential scalar?

Electric potential is the scalar quantity because it is **defined as the amount of work done to bring a unit positive charge to bring from infinity to the point under the influence of the primary charge**. Work is a scalar as it is a dot product of force and displacement.
