Question

Kirchhoff's Second Law is based on law of conservation of:

• A. Charge
• B. Energy
• C. Momentum
• D. Mass and Energy

Hint:

Loop rule = energy conservation, Junction rule = charge conservation.

Answer 1

The Correct Option is B

Kirchhoff’s Second Law (Loop Rule) states that the sum of potential differences in any closed loop is zero. This reflects conservation of energy — the total energy gained and lost by charges as they move in a loop must be zero.
