Kirchhoff's Voltage Law (KVL)

It states that "In a closed loop of an electric circuit, the algebraic sum of the EMFS is equal to the algebraic sum of the potential drops".

Kirchhoff's Current Law (KCL)

It states that the algebraic sum of currents entering a node is equal to the algebraic sum of currents leaving a node.

Ohm's Law

Ohm's law states that the current through a conductor is directly proportional to the voltage applied across it, provided the temperature remains constant.

V = I × R

Lenz Law

Lenz's Law states that the direction of an induced current is such that it opposes the change in magnetic flux that caused it. This is a consequence of the conservation of energy and Faraday’s Law of Electromagnetic Induction.
