Depends. What did you want to measure? If it's voltage drop across the incandescent element, then you had better hook up your infinite resistance voltmeter in parallel with the lamp.
One does NOT insert a voltmeter in a series cirtcuit...an ammeter can be inserted in series, though. A voltmeter is connected in parallel with the source voltage and low(ground) side.
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
The voltmeter is connected parallel to the circuit in order to measure the voltage drop across that circuit or sub-circuit. If you were to connect the volmeter series to the circuit, since it is a high impedance device, it would represent an effective open-circuit condition. You would see the voltage available to the circuit, but the circuit would not receive its intended current and it would not function. Contrast this with the ammeter, which you do place series to the circuit in order to measure the current flow through the circuit.
Voltmeters must be connected in parallel with the component or section of the circuit where the voltage is to be measured. This parallel connection allows the voltmeter to measure the potential difference across the component without significantly affecting the circuit's operation. It is important to ensure that the voltmeter has a high internal resistance to minimize the current flowing through it and avoid altering the circuit behavior.
If you are asking how a voltmeter should be connected in a circuit, then the answer is that it should be connected in parallel with the device across which you want to determine the voltage. This applies whether the circuit is d.c. or a.c.

Voltmeter should be connected always in parallel to a circuit ANSWER : IT should be in parallel except when used to measure current. Then it should be placed in series across a shunt.
A voltmeter can be connected in parallel with each component in a parallel circuit to measure the voltage across that specific component. By connecting the voltmeter in parallel, it allows the voltmeter to measure the voltage drop across the component without affecting the overall circuit.
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
A voltmeter is connected in parallel in an electrical circuit to measure the voltage across a specific component or part of the circuit without affecting the flow of current through the circuit.
in parallel
Connect ammeter in series and voltmeter in parallel to the circuit
Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.
