Ohm's Law Calculator

Ohm's law calculator: calculates the relation between Voltage, Current and Resistance.

Enter 2 values to get the third value and press the Calculate button:

	Enter Resistance:	R	=		Ohms [Ω]
	Enter Current:	I	=		Amps [A]
	Enter Voltage:	V	=		Volts [V]

Resistance calculation

R = V / I

Current calculation

I = V / R

Voltage calculation

V = I × R
