# Electric Potential Energy

Written by Jerry Ratzlaff on . Posted in Electromagnetism

Electric potential energy ( $$U_e$$ ) (also known as electrostatic potential energy) is the energy or force that is required to move a charge in resistance to an electric field.

### Electric Potential Energy formula

$$\large{ U_e = \frac {k q_1 q_2}{r} }$$

Where:

$$\large{ U_e }$$ = electric potential energy

$$\large{ k }$$ = Coulomb's constant

$$\large{ q_1 }$$ = electric charge

$$\large{ q_2 }$$ = electric charge

$$\large{ r }$$ = radius

## Voltage Electric Potential Energy

Electric potential energy ( $$V$$ ) known as voltage, is when two opposite charges are held apart.

### Voltage Electric Potential Energy formula

$$\large{ V = \frac {W}{C} }$$

Where:

$$\large{ V }$$ = voltage or electric potential energy

$$\large{ W }$$ = work

$$\large{ C }$$ = charge
