Kirchhoff's Voltage Law (KVL):
ASum of currents = 0
BEnergy never conserved
CRandom
DAlgebraic sum of voltage drops around any closed loop = 0
Answer & Solution
Correct answer: D. Algebraic sum of voltage drops around any closed loop = 0
KVL: ΣV around any closed loop = 0. Based on energy conservation (no net energy created/destroyed in closing the loop). Used in mesh analysis.
