Kirchhoff's second law for an electric network is based on:
- A Law of conservation of mass
- B Law of conservation of charge
- C Law of conservation of energy
- D Law of conservation of momentum
Answer & Solution
Correct Answer
(C) Law of conservation of energy
Step-by-step Solution
Detailed explanation
Law of conservation of energy Kirchhoff's second law, also known as Kirchhoff's Voltage Law (KVL), states that the sum of the electromotive forces (emf) and the product of currents and resistances around any closed loop in a network is zero. This law is based on the law of…
