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.
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.
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.
To measure Voltage which is the force pushing current :)

the purpose of a voltmeter is used to measure voltage in a circuit
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
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 is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
A voltmeter is used to measure potential difference across two points in an electrical circuit . The voltmeter is connected in parallel across the circuit element (resistance ) so that its inclusion in the circuit has negligible effect on total resistance and current flowing in yhe circuit A voltmeter has high resistance,if connected in series it will increase of circuit and reduce the current in the circuit

In parallell.
yes, voltmeter drops to zero as current increases to maximum
