Ohm's Law
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.
The rate of the flow of the current is equal to electromotive force divided by resistance. The following symbols are used:
I = Intensity of Current = Amperes
E = Electromotive Force = Volts
R = Resistance = Ohms
P or W = Power = Watts
