Assertion: voltmeter's impedance | /r/HasProperty | infinite
Facets:
Source sentences:
text: Ideally a voltmeter should have infinite impedance, which means it must not draw any current from the circuit.
text: Ideally voltmeters should have infinite impedance, but this is not the case with actual voltmeter; they have a finite resistance value.
text: Ideally the measuring device should not affect the circuit parameters i.e., the internal impedance of the ammeter should be zero (no voltage drop over the ammeter) and the internal impedance of the voltmeter should be infinite (no current through the voltmeter).
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.
