Question

In the question given below, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R) just below it. Of the statements mark the correct answer.

Assertion (A): At any junction of a network , the algebraic sum of various currents is zero.

Reason (R): At steady state , there is no accumulation of charges at the junction.

• A. Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.
• B. Both 'A' and 'R' are true and 'R' is not the correct explanation of 'A'
• C. 'A' is true and 'R' is false
• D. 'A' is false and 'R' is true

Answer 1

The correct option is A Both 'A' and 'R' are true and 'R' is the correct explanation of 'A'.

From the statement of Kirchhoff's junction law, "Sum of all the incoming currents is equal to sum of all outgoing currents at a junction" , when the circuit is in its steady state.
