when we connected voltmeter in series it takes large current and voltage and the resistance is considerably decreases.this is why we had connected voltmeter in series combination.

What happens if you energize power to wire on n.c. contacts?
If the relay contacts are in series with a connected load, then the load will energize.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
How wattmeter is connected in circuit?
A wattmeter has two coils: a current coil and a voltage coil. The current coil is connected in series with the load, while the voltage coil is connected in parallel with the load (just in the same way an ammeter and a voltmeter are connected). The wattmeter's polarity markings must be observed while making these connections -if the wattmeter reads 'downscale' (backwards), then the connection to either one (but not both) of the coils must be reversed.
How is an multimeter connected to take a measure?
Multimetres are generaly used to measure the following quantities. Voltage: multimeter is connected in parallel with the Load; Current: multimeter is connected in series with Load; Resistance: the resistor must be taken out of the circuit first, then, the probes from the multimeter are connected across the resistor,
What would happen if a voltmeter were substituted for an ammeter?
Smoke. Since a voltmeter is in parallel with the load it is right across the source voltage. Putting the amp meter across the line with its low resistance it will act like a fuse, hence the smoke. Newer solid state testers are usually smarter that the operators. They have built in circuitry which sense the wrong settings you are using and shut the tester off with a "beep" to let you know that you are doing something wrong.
How is ammeter and voltmeter attached to a 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.
How are voltmeter connected to circuit?
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 .
Where does the volmeter and ammeter go in a circuit?
after incomer & before outgoing feeder, we connect ameter to measure amps.AnswerThe voltmeter is connected in parallel with the load and the ammeter is connected in series with the load, if you wish to measure the potential difference across, and the current through, that load.
What happens if you energize power to wire on n.c. contacts?
If the relay contacts are in series with a connected load, then the load will energize.
The rules of connecting voltmeter and ammeters in the circuit?
Connect ammeter in series and voltmeter in parallel to the circuit
How ammeter connected?
In series with a load.
How current coil is connected in energy meter?
It's connected in series with the load.
How should a voltmeter be connected to measure voltage of a component?
Since voltage is electrical potential difference, to measure the voltage across a component, you place the voltmeter across, or in parallel with, the component.
How wattmeter is connected in circuit?
A wattmeter has two coils: a current coil and a voltage coil. The current coil is connected in series with the load, while the voltage coil is connected in parallel with the load (just in the same way an ammeter and a voltmeter are connected). The wattmeter's polarity markings must be observed while making these connections -if the wattmeter reads 'downscale' (backwards), then the connection to either one (but not both) of the coils must be reversed.
Will the voltmeter work when ammeter is connected wrongly in a circuit?
The volt meter should work. The meter is connected across the supply where as the amp meter is connected in series with any load that it is metering. On larger installations to measure the amperage, a current transformer is connected around the conductor to be monitored. If a CT is used then the polarity has to be observed when connecting to an amp meter.
If a voltmeter is hooked up in series it will?
It will prevent almost all current from flowing the circuit, since a voltmeter has a very high electrical resistance. Only ammeters (or milliammeters) should be wired in series between a power source and its load.
Will a voltmeter tell you if a load is on?
No
