Changing the resistance of a voltmeter
jambaugh - That's what I assumed. If that's the main point perhaps I'm missing something. Could you clarify? The confusing issue is what the voltmeter does when it has a finite resistance. Does it act like a resistor in parallel? Or is it a resistor in series as rl.baht seems to be saying...- pp280

Changing the resistance of a voltmeter
The setup shows a Galvanic cell connected to a voltmeter. The question asks how the reading of the voltmeter would change if the voltmeter's resistance became finite (instead of infinite) and current started to pass through the voltmeter. The answer given is "The reading will decrease because...- pp280
