Assertion :All electric devices shown in the circuit are ideal. The reading of each of ammeter (a) and voltmeter (V) is zero. Reason: An ideal voltmeter draws almost no current due to very large resistance, and hence (V) and (a) will read zero.

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
An ideal voltmeter has infinite resistance, so that it draws no current from the circuit under test. Hence the reading of ammeter will be zero as well as voltmeter will be zero too.
