Which pair correctly matches the law with its physical basis?
AKCL - conservation of energy; KVL - conservation of charge
BKCL - conservation of resistance; KVL - conservation of current
CKCL - conservation of charge; KVL - conservation of energy
DKCL - conservation of momentum; KVL - conservation of mass
Answer & Solution
Correct answer: C. KCL - conservation of charge; KVL - conservation of energy
KCL comes from conservation of charge at a node, while KVL comes from conservation of energy around a closed loop. The other pairings mismatch the physical principles.
