Which statement best distinguishes Kirchhoff's Current Law from Kirchhoff's Voltage Law?
AKCL applies to junctions and current balance, while KVL applies to closed loops and voltage balance.
BKCL applies only to batteries, while KVL applies only to resistors.
CKCL is used only in AC circuits, while KVL is used only in DC circuits.
DKCL measures power, while KVL measures charge.
Answer & Solution
Correct answer: A. KCL applies to junctions and current balance, while KVL applies to closed loops and voltage balance.
KCL concerns how current is conserved at a node or junction. KVL concerns how voltage rises and drops balance around a closed loop. The other choices incorrectly restrict the laws or confuse the physical quantities involved.
