Consider the following two statements:
I. Kirchhoff's junction law follows from the conservation of charge.
II. Kirchhoff's loop law follows from the conservation of energy.
Which of the following is correct?
I. Kirchhoff's junction law follows from the conservation of charge.
II. Kirchhoff's loop law follows from the conservation of energy.
Which of the following is correct?
View answer and explanation
Correct option: D
Both I and II are correct
Option D is correct. Kirchhoff's junction law is based on the conservation of charge, and Kirchhoff's loop law is based on the conservation of energy.
