Vedclass · Answer

(A) voltmeter is a device used to measure the potential difference between two points in an electrical circuit.To measure the potential difference,it must be connected in parallel across the component.$A$ voltmeter is designed to have a very high resistance so that it draws negligible current from the circuit.If the resistance were low,it would draw significant current,thereby altering the potential difference it is intended to measure.Since the high resistance of the voltmeter is the specific reason why it is connected in parallel to avoid disturbing the circuit,the Reason is the correct explanation of the Assertion.

Assertion: Voltmeter is connected in parallel with the circuit.
Reason: Resistance of a voltmeter is very large.
