A voltmeter is used to measure the voltage difference in between the two different points of a resistor. But it should not affect the amount of current that is flowing through the element that is in between those two points. So, a voltmeter should have high resistance so that the current does not get drawn through it.
However, an ideal ammeter has almost zero internal resistance. This is because it should be able to drop even the little possible voltage as the electrons usually flow through it.
So, to get a resistance on a circuit, the voltmeter is usually connected in a parallel direction to the circuit. This is because the voltmeter should not load the circuit and the objects in parallel will have the same potential difference. An ammeter should be connected in series with the to-be-measured circuit.
If the voltmeter is in series and the ammeter is in parallel, then the potential difference will be zero and the current flowing through the circuit will be divided into many different branches.
