Ohms Law calculator for calculating V I R formulas. Enter any two known values to calculate the other two.
V = Voltage
I = Current
R = Resistance
P = Power
An Ohm's Law calculator to calculate V, I, R & P (Voltage, Current, Resistance & Power)
V = Voltage measured in Volts
I = Current measured in Amps
R = Resistance measured in Ohms
P = Power measured in Watts
Ohm's law states that the electrical current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship.
