State Kirchhoff's two laws and say what conservation principle each expresses.
Original Khojo Papers practice question — not from a past board paper.
Answer
The junction rule states that the algebraic sum of the currents meeting at a junction is zero, which expresses the conservation of charge. The loop rule states that round any closed loop the algebraic sum of the changes in potential is zero, which expresses the conservation of energy.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Together they solve any network that Ohm's law alone cannot.
