Ohm's Law

The amount of current flowing in a circuit made up of pure resistance is directly proportional to the electromotive forces impressed on the circuit and inversely proportional to the total resistance of the circuit.

By formula, Voltage is equal to Current (in amperes) times Resistance (in Ohms), or V = I x R


V = I x R
= x
R = V / I
= /
I = V / R
= /
