Definition
Kirchhoff's Loop Rule, also known as Kirchhoff's Voltage Law (KVL), states that the sum of the voltage drops around any closed loop in a circuit is equal to the sum of the voltage sources in that loop.
It relates current, voltage, and resistance in a circuit and states that current is directly proportional to voltage and inversely proportional to resistance.
Electric Circuit: A path through which electric current can flow, consisting of various components such as resistors, capacitors, and batteries connected by conductive wires.
