Ohm's Law states...?

• The current flowing through a conductor in a closed circuit is directly proportional to the resistance of the conductor and inversely proportional to its potential.

• The current flowing through a conductor in a closed circuit is directly proportional to the potential difference and inversely proportional to the resistance of the conductor.

• The electric current flowing depends on the strength of the power source generated by the generator.

• The electric current flowing through a conductor is directly proportional to the magnitude of the magnetic flux between two points in the circuit.

• The current flowing depends on the magnitude of the source current inversely proportional to the load.
