Kirchhoff's junction rule

Definition

Kirchhoff's junction rule, also known as Kirchhoff's first law or the conservation of electric charge, states that the total current flowing into a junction in an electrical circuit is equal to the total current flowing out of the junction. In other words, electric charge is conserved at a junction point in a circuit.
