You connect a voltmeter in parallel with the circuit on which you want to read the voltage.

You should always connect a voltmeter in parallel.
Description: A voltmeter is a high resistance device. If I connect this in series, potential drop across the voltmeter would be high and it effects the potential drop across the part which you have to measure. This is in accordance with Kirchhoff's 2nd rule or Loop rule.

Voltage is the difference in potential between two points in the circuit, therefore you connect the meter across the two points in parallel. Current is a measure of flow -- you'd connect a meter in series to measure the flow.

It would need to connect in parralel to read from the positive and negative (DC Voltage) or Live and Neutral (AC Voltage)

Parallel - also, voltmeters have high resistance to minimize current to flow through them.

A VOLTMETER IS USED TO MEASURE THE POTENTIAL DIFFERENCE IN A CIRCUIT
SO IT IS PLACED IN PARALLEL TO THE CIRCUIT COMPONENT TO MEASURE VOLTAGE ACROSS IT .
TO MEASURE CURRENT WE USE AN AMMETER IN SERIES WITH THE CIRCUIT.

A Volt-meter is always connected 'ACROSS' a circuit i.e. in Parallel.

voltmeters in paralell
ammetters and wattmetter is series

You'd want to connect it in parallel, because potential differences are the same in parallel.
