Ohm's law formula calculator

Ohm's law formula calculator allows you to calculate strength of electric current, voltage and resistance in a part of electrical circuit by using the Ohm's law.

Calculate by Ohm's law

Voltage (U): Volt
Resistance (R): Ohm

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to resistance of the conductor,
where I - strength of electrical current, U - voltage, R - resistance of the conductor
