To ensure that very little current flows through it.

Vedclass · Answer

(B) voltmeter is connected in parallel to the component across which the potential difference is to be measured. If the resistance of the voltmeter is low,it would draw a significant amount of current from the circuit,thereby altering the potential difference it is intended to measure. By keeping the resistance of the voltmeter very high,it draws negligible current from the circuit,ensuring that the potential difference across the component remains practically unchanged.

Why is the total resistance of a voltmeter kept very high?
