alleryStart learning →Kirchhoff's Current Law (KCL) is a statement of which conservation principle?
AConservation of voltage around a loop
BConservation of momentum at a node
CConservation of magnetic flux per turn
DConservation of electric charge at a node
Answer & Solution
Correct answer: D. Conservation of electric charge at a node
KCL: algebraic sum of currents entering a node = 0. Follows from charge conservation: no charge accumulates at a node in lumped-element models.
