## Electric Potential :

We saw in work and energy that Potential energy refer to the energy stored in a body that can be converted to a kinematic energy Here we apply the same context in electricity

So the Electric potential the electrical potential , the energy neede to move a point charge tought a distance r and it is calculated by

W: Work done to move the charge

q: the electrical charge

k: coulomb's constant

### Superposition principal

The same principal apply as with force, and electrical field the potential in a field is the equal to the sum of all electrical potentials of all charges

V = V1 + V2 + V3 + ......etc
