Because, by definition, a voltage is the difference in potential between two different points. So the voltmeter must be connected across those points in order to measure that voltage -i.e. in parallel with the points.B
voltmeter internal resistance is very high , nearly equal to open circuit
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
Connect ammeter in series and voltmeter in parallel to the circuit
A voltmeter needs to be connected in parallel with the part of the circuit you are checking. It records a change in voltage, and has a high internal resistance, so it cannot be connected in series unless you want to screw up the circuit. Set the meter to AC or DC volts and place the wires of the terminal across the resistor, switch, or any other potentially resistive part of the circuit.
ammeter in series at any side as required since it is bilateral and voltmeter is connected in parallel to measure voltage drop across it
No, an ammeter should never be placed in parallel with a component - it should always be placed in series, so that the current through the component is measured.If you place an ammeter in parallel with a component, you create a short circuit around the component. Depending on the rest of the circuit, you could damage the circuit, damage the ammeter, create a fire, etc. You certainly will affect the current through the component, and that is not what you want to accomplish.

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.
in parallel
A voltmeter should be connected in a parallel connection
A voltmeter is a device to measure the voltage in a electric circuit, and must have be connected in parallel to it.
Usually a voltmeter is connected across the load whether or not it is AC (Alternating current) or DC (Direct Current). A voltmeter is never connected in series with the load as this may cause serious injury or damage. The meter will absorb the full potential .
Connect ammeter in series and voltmeter in parallel to the circuit
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.
The voltmeter is connected in parallel between the two points whose potential difference is required.
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
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.
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.
