Which of the following best distinguishes Kirchhoff's Current Law from Kirchhoff's Voltage Law?
AKCL applies at a junction, while KVL applies around a closed loop
BKCL applies only to batteries, while KVL applies only to resistors
CKCL is based on energy conservation, while KVL is based on charge conservation
DKCL and KVL are the same law written differently
Answer & Solution
Correct answer: A. KCL applies at a junction, while KVL applies around a closed loop
KCL is a node law: it relates currents entering and leaving a junction. KVL is a loop law: it relates voltage rises and drops around a closed path. Option C reverses their physical basis.
