Which statement best distinguishes Kirchhoff's Current Law from Kirchhoff's Voltage Law?
AKCL applies to a junction and KVL applies to a closed loop
BKCL applies only to resistors and KVL applies only to sources
CKCL is based on conservation of energy and KVL on conservation of charge
DBoth laws apply only when current is zero
Answer & Solution
Correct answer: A. KCL applies to a junction and KVL applies to a closed loop
KCL concerns currents meeting at a node or junction, while KVL concerns potential changes around a closed loop. Also, KCL is associated with conservation of charge, and KVL with conservation of energy, so option C reverses them.
