E=IR; I=E/R; R=E/I; Where E = Voltage impressed on a circuit, I = current flowing in a circuit and R = circuit resistance. Ohm’s Law is used for calculating voltage drop, fault current and other characteristics of an electrical circuit.

A unit of electrical resistance defined as the resistance of a circuit with a voltage of one volt and a current flow of one ampere.

Overhead Line
