Lienard Wiechert Electric Potential Calculator

The effect of electromagnetic effect of a moving point charge is described by the Lienard Wiechert potential in terms of vector and scalar potential. In this calculator, the scalar potential termed as electric potential of a moving point charge is calculated based on the values permittivity of free space, velocity, vector from charge to point and finite speed.

Formula:

Φ= q / ((4*π*ε0) * (|r|-(v*r/c))) Where, Φ = Electrical Potential q = Charge εo = Permittivity Of Vacuum r = Vector From Charge To Point v = Particle Velocity c = Speed Of Light
