Vedclass · Answer

(D) In the given circuit, the battery $E$, ammeter $A$, resistor $R$, and voltmeter $V$ are connected in series.An ideal voltmeter has infinite resistance, which prevents any current from flowing through the circuit.Since the circuit is effectively open due to the infinite resistance of the ideal voltmeter, the current $I$ flowing through the ammeter is $I = \frac{E}{R + R_V} = \frac{E}{R + \infty} = 0$.Therefore, the ammeter reading is $0$.The voltmeter is connected in series with the rest of the circuit. The potential difference across the ideal voltmeter will be the entire $EMF$ of the battery, $V = E$. Thus, the voltmeter reading is not zero.Therefore, the Assertion is incorrect, and the Reason is also incorrect.

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.
