Kirchhoff's Current Law, also known as KCL, states that the total current entering a junction or node in an electrical circuit is equal to the total current leaving that junction. In other words, the sum of currents flowing into a point in a circuit is equal to the sum of currents flowing out of that point.
This law relates voltage, current, and resistance in an electrical circuit. It states that the current through a conductor between two points is directly proportional to the voltage across those points and inversely proportional to the resistance.
KVL states that in any closed loop or mesh within an electrical circuit, the algebraic sum of all voltages is zero.
Node: A node refers to any point where two or more components are connected together in an electrical circuit. It can be thought of as a junction where currents meet and split.
