Assertion:- Kirchhoff's voltage law indicates that field is conservative.
Reason:- Potential difference between two points in a circuit does not depend on path

Options

A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true

Answer

A

Explanation

Kirchhoff.s voltage law says that the sum of the voltages around any closed loop is zero. A closed loop starts from a node, traces a path through the circuit and returns to the same node. Since the total work done in moving a charge around this close path the zero, hence the electric field is conservative. So, the assertion is true.
Potential difference between two points in a circuit does not depend on the path. This is true for conservative field. Hence the reason is also true and it explains the assertion.
