Why does a voltmeter have infinite resistance. When the voltage is measured using a voltmeter in a circuit it should not alter the quality of the measurement. When a high resistance or ideally infinite resistance voltmeter is used there will not be any current flow through the voltmeter. Therefore the correct value of the voltage can be measured.
