Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R): I = V/R

• It is named after German physicist Georg Simon Ohm

• It is commonly used in electrical engineering to calculate current, voltage, and resistance in circuits
