Ohm's Law (1827)

According to Ohm's Law, the current that flows through a conductor between two locations is inversely proportional to the conductor's resistance and directly proportional to the voltage across the two points.

Faraday's Law (1831)

According to Faraday's Law of Electromagnetic Induction, an electromotive force (EMF) is induced in a closed loop when the magnetic field changes. The rate at which the magnetic flux changes through the loop is directly correlated with this produced EMF.

Lenz's Law (1834)

According to Lenz's Law, in a closed loop, the induced current (also known as the electromotive force, or EMF) will always flow in the opposite direction of the change in magnetic flux that generated it. This is a result of the energy conservation concept.
