Question
Write the statements of Kirchhoff's laws.

Answer

The statements of Kirchhoff"s laws are as follows:
(1) Junction rule : "At any junction, the sum of the currents entering the junction is equal to the sum of currents leaving the junction."
(2) Loop rule : "The algebraic sum of changes in potential around any closed loop involving resistors and cells in the loop is zero."
Kirchhoff's junction rule works on the law of conservation of charge and loop rule works on the law of conservation of energy.
