Source sentences:
text: Ideally voltmeters should have infinite impedance, but this is not the case with actual voltmeter; they have a finite resistance value.
text: The main problem involving voltmeters is that, they have a finite resistance value; ideally, a voltmeter should have infinite impedance, which means it must not draw any current from the circuit.
