As we know all about Kirchhoff’s law. It is the fundamental law to circuit theory. This law quantifies that how charge flows through a circuit and how voltage varies around a loop. According to Kirchhoff’s first law (current law or conservation of charge), charge flowing into a junction must be equal to current flowing out of it. Kirchhoff’s 2nd law (voltage law or conservation of energy), the sum of all voltage around any closed loop of a circuit must be equals zero The sum of emfs and potential differences around a closed loop equals zero is a consequence of conservation of charge and also that conservation of energy.
