Kirchhoff's Laws & Measuring Instruments
Consider the following two statements.
(A) Kirchoff's junction law follows from the conservation of charge.
(B) Kirchhoff's loop law follows from the conservation of energy.
Which of the following is correct?
Show answer and solution
Answer: (d)
- (A) Junction law: charge cannot pile up at a junction, so it follows from conservation of charge. Correct.
- (B) Loop law: net work on a charge round a closed loop is zero, so it follows from conservation of energy. Correct.
- So the answer is (d) both are correct.
