Q. With reference to Voltmeter and Ammeter, consider the following statements:
While a Voltmeter is connected in series in a circuit; Ammeter is connected in parallel
While resistance of an ideal voltmeter is infinity; resistance of an ideal ammeter is zero
Which among the above is / are correct statements? Answer:
Only 2
Notes:
While a Voltmeter is connected in parallel in a circuit; Ammeter is connected in series: This statement is incorrect. A voltmeter is connected in parallel in a circuit to measure voltage across a component. An ammeter is connected in series in the circuit to measure current flow through a component.
While resistance of an ideal voltmeter is infinity; resistance of an ideal ammeter is zero: This statement is correct. An ideal voltmeter has infinite internal resistance allowing voltage to be measured without current draw. An ideal ammeter has zero internal resistance allowing all circuit current to flow through it to be measured.
