Assertion: In the circuit shown in figur...


Assertion: In the circuit shown in figure after closing the switch `S` reading of ammeter will increase while that of voltmeter will decrease.
Reason : Net resistance decreases as parallel combination of resistors is increased,

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Since net resistance decreases, therefore main current increases Hence, net potential difference across voltmeter also increases.
