It would be equivalent to adding a high value resistor (>10M ohms) in series in the circuit. Voltmeters typically present a high internal impedance so as to not change the current flow in the circuit you are tying to measure.
the circuit wont work the voltmeter only takes a voltage reading power does not actually pass through the meter
sometimes it can be used to measure very low leakage current using the hi impedance of the meter. EXAMPLE leakage offset from an amplifier. it could be into the nanoamps.

∙ 12y agoAn ammeter is a low impedance device, intended to be placed in series with the part of the circuit that is being measured.
A voltmeter, on the other hand, is a high impedance device, intended to be placed in parallel with the part of the circuit that is being measured.
If you connect an ammeter in parallel with a voltmeter, the ammeter will short out the voltmeter, and the voltmeter will effectively read zero.
Worse, if the ammeter is connected in parallel with a part of the circuit, you also will short out that part, and the circuit will pull high current, blowing the fuse or circuit breaker, or causing damage to various components - at the very least, causing abnormal behavior.

∙ 11y agoAn ammeter has a very low resistance, and a voltmeter has a very high resistance. So the ammeter will short circuit the supply, while the voltmeter will significantly increase the resistance of the load.

∙ 11y agoConnecting an ammeter in parallel acros a voltage source is as same as short circuit. It will draw huge fault current and may damage the meter and may result into injury to the persons involved.
Normally an ammeter is provided with a small fuse to protect the meter in such accidental cases.

∙ 13y agoit wont measure the resistance unless its also a ohm meter. i doubt it can break

Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
Why wouldn't the shunt resistor in the ammeter protect the ammeter when the ammeter is connected in parallel?
Connecting an ammeter in parallel subjects that ammeter to the full supply voltage. The shunt resistor is not designed to sustain that value of voltage and will burn out. Also, the clue is in the word 'shunt' (which means 'in parallel') which means that the coil will also burn out!
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.
Why do you have specific resistance combination inside a voltmeter and an ammeter Explain?
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
Why in an ammeter low resistance is connected in parallel with the coil?
For protection.. Since the current prefer the short cut ..
Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
Why should ammeter still be connected in a series despite the fact that the bulbs are already connected in parallel?
Because the ammeter connected in parallel will act as a short circuit.
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
What happens if an ammeter is connected in parallel and voltmeter connected in series in a circuit?
The voltmeter will register the volts, the ammeter will either explode or blow a fuse since it has a very low resistance and is designed to be used in series to measure the current flowing through it.
Why wouldn't the shunt resistor in the ammeter protect the ammeter when the ammeter is connected in parallel?
Connecting an ammeter in parallel subjects that ammeter to the full supply voltage. The shunt resistor is not designed to sustain that value of voltage and will burn out. Also, the clue is in the word 'shunt' (which means 'in parallel') which means that the coil will also burn out!
How shunt helps to extend the range of ammeter?
A shunt is connected in parallel with an ammeter. Any current applied to parallel devices will divide betwen them, so the ammeter will pass only a part of the total current.
What happens when an ammeter is connected in parallel with a circuit?
SMOKE!!! Yiii-haaaa! An ammeter is always as low a resistance as possible. That way, the current that you measure in a circuit using the meter will be the same as if the meter were not there. So putting an ammeter in parallel with a circuit means that you just short circuited the circuit you were intending to measure. Poof! There goes your ammeter!An ammeter has a very low internal resistance. So, if it is connected in parallel with a load, it will short-out that load. The resulting high current flowing through the ammeter may severely damage the meter (and possible harm the user), although most are fitted with fuses to protect them.

How you convert galvanometer into ammeter in detail?
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
Why do you have specific resistance combination inside a voltmeter and an ammeter Explain?
in voltmeter we have internal Resistance and connected in series , to current don't transfer in voltmeter , and we have internal resistance in ammeter and connected in parallel , to most current transfer through the ammeter.
What happens when a bulb ammeter battery and switch are put connected together?
the bulb will glow and ammeter will show the reading
