MCQ
Kirchoff's junction law is equivalent to $......$.
  • A
    Conservation of energy.
  • ✓
    Conservation of charge.
  • C
    Conservation of electric potential.
  • D
    Conservation of electric flux.
✓

Answer

Correct option: B.
Conservation of charge.

Kirchhoff's junction rule is an application of the principle of conservation of electric charge: current is flow of charge per time, and if current is constant, that which flows into a point in a circuit must equal that which flows out of it.
