Question

Kirchhoff’s voltage law is a consequence of?

• A. Conservation of energy
• B. Conservation of charge
• C. Quantization of energy
• D. Quantization of charge

Answer 1

Answer: (A)

Conservation of energy

It is a consequence of conservation of energy. A charge going around a circuit loop returns to its initial position. And the force on this charge is conservative. What does that mean? Zero net work is done on the charge in the closed loop. It’s total energy remains conserved.
