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.
