Electric Potential Calculator

Your details

Choose what to solve for. All modes use the same formula V = kq/r.
Magnitude and sign of the point charge. Negative values give negative potential.
µC
Distance from the point charge to the observation point.
m
Relative permittivity of the surrounding medium. In any medium V = kq / (er * r).
Electric potential V
179,751.0358V

Electrostatic potential at the observation point

Potential (auto-scaled)179.7510 kV
Electric field E1,797,510.3585V/m
Potential energy U179,751.0358J
Electric potential V (V)179,751.0358
Electric field E (V/m)1,797,510.3585

Electric potential: 179.7510 kV

  • Positive potential: a positive test charge placed here would naturally move away from the source.
  • The electric field magnitude at this point is 1.798e+6 V/m. E = V / r because V = kq/r and E = kq/r^2 share the same kq factor.

Next stepTo find the work done moving a charge Q between two points, multiply Q by the potential difference: W = Q * deltaV.
