Which pair correctly matches the law with the quantity conserved?
AKCL - energy, KVL - charge
BKCL - charge, KVL - energy
CKCL - momentum, KVL - mass
DKCL - resistance, KVL - current
Answer & Solution
Correct answer: B. KCL - charge, KVL - energy
KCL is based on conservation of charge at a junction, while KVL is based on conservation of energy around a closed loop. This pairing is the correct conceptual match.
