`V = k(q/r)`

Enter a value for all fields

The **Electric Potential** equation is used to calculate the Electric Potential(**V**) using Coulomb's Constant(**k**), the charge(**q**), and the distance(**r**).

**INSTRUCTIONS:** Choose and enter the following units:

**(q)**The magnitude of the charges**(r)**The distance between the charges

*You don't need to enter k for Coulomb's Constant since it is already calculated for you.

The potential energy associated with a varying force is **Electric Potential**. The following formula is commonly used to calculate Electric Potential: `V = k*(q/r)` where:

- V = Electric potential
- k = Coulomb's Constant
- q = charge
- r = distance

Coulomb's Constant may be more familiar in the form:

`1/(4piepsilon_0)`

where `epsilon_0` is the permittivity of free space.
