Electric Potential Calculator
Find the electric potential from a point charge.
Electric potential is the work per unit charge to bring a charge from infinity to a point.
The math behind it
V = k·Q ÷ r. Unlike the field, potential falls off as 1/r, not 1/r².
Worked example
1 µC at 0.5 m → about 17,975 V.
FAQ
Potential vs field?
Potential is a scalar (volts); the field is its spatial rate of change (V/m).
