Question

Consider the following two statements:-

(A) Kirchhoff's junction law follows from conservation of charge.

(B) Kirchhoff's loop law follows from conservative nature of electric field.

Options

  • A and B are correct

  • A is correct but B is wrong

  • B is correct but A is wrong

  • A and B are wrong

MCQ

Solution

A and B are correct

 

According to Kirchhoff's junction law, the net charge coming towards a point should be equal to the net charge going away from that point in the same time. It follows from the principle of conservation of charge.

The loop law follows from the fact that electrostatic force is a conservative force and the work done by it in any closed path is zero.
