Answer:

An perfect voltmeter has infinite resistance. As stare the effect it has on the circuit a voltmeter acts like dry air unlike an ammeter which acts like a piece of wire. A voltmeter has two investigate one marked positive and the other negative. If you connect the positive investigate to point A in the circuit and the other to point B in the circuit the voltmeter shows how much higher the electric potential at A is than that at point B. (Some however not all voltmeters allow for negative readings. Point A mortal at a potential that is -5 Volts higher than the potential at point B is the same as point B being at a potential that is 5 Volts higher than the potential at point A.) Taking a voltage analysis is a passive activity. There is no require to modify the circuit prior to connecting the voltmeter. One easy touches or connects each probe to a point in the circuit.
