Electric Potential Calculator
Calculate electric potential (voltage) at a point in an electric field
Method 1: From Point Charge
Method 2: From Work Done
Electric Potential Formulas
Point Charge: V = k * Q / r
From Work: V = W / q
Potential Energy: U = k * Q * q / r = q * V
k = 8.99 x 10⁹ N·m²/C² (Coulomb's constant)
