What is the Electric Potential Calculator & How does it work?
Electric potential at a point in space due to a point charge is the amount of work done per unit charge to bring a test charge from infinity to that point. The electric potential ( V ) at a distance ( r ) from a point charge ( q ) is given by Coulomb’s law for electric potential.
The formula for electric potential is:
V = k cdot frac{q}{r}
k = Coulomb’s constant (approximately (9.0 times 10^9 , text{N} cdot text{m}^2/text{C}^2))
q = Charge of the point source in coulombs (C)
r = Distance from the point charge to the location where potential is being calculated in meters (m)

Frequently Asked Questions
What is electric potential?
Electric potential is the amount of work done per unit charge to bring a test charge from infinity to a specific point in an electric field.
How do I use this calculator?
Enter the charge of the point source and the distance from the point charge to calculate the electric potential.
What is Coulomb’s constant?
Coulomb’s constant (k) is approximately (9.0 imes 10^9 , ext{N} cdot ext{m}^2/ ext{C}^2), used in the formula for electric potential.
What units should I use for charge and distance?
Use coulombs (C) for charge and meters (m) for distance to get the potential in volts (V).
Can this calculator handle negative charges?
Yes, you can input negative values for charge. The sign will affect the direction of the electric field.
What is the formula for electric potential?
The formula is ( V = k cdot frac{q}{r} ), where ( k ) is Coulomb’s constant, ( q ) is the charge, and ( r ) is the distance.
How does electric potential relate to electric field?
Electric potential is related to the electric field by the gradient: the electric field is the negative gradient of the electric potential.
