For complicated circuits, Kirchoff’s laws can be used to find current or voltage. There are two generalised laws :

Kirchoff’s first law (current law): Kirchoff’s current law states that the algebraic sum of the currents meeting at any junction in a circuit is zero.

Kirchoff’s second law (voltage law): Kirchoff’s voltage law states that the algebraic sum of the products of resistance and current in each part of any closed circuit is equal to the algebraic sum of the emf’s in that closed circuit. This law is a consequence of conservation of energy.
