The ammeter is used in series, because you want to measure the current through a circuit. The voltmeter is used in parallel, because you want to measure the voltage across a circuit.
If you were to place the voltmeter in series, no current would flow because of the relatively high impedance of the voltmeter.
If you were to place the ammeter in parallel, you would create a short-circuit, due to the relatively low impedance of the ammeter.

∙ 13y agoA: There is no difference. Both read voltage. The interpretation is however is difference. The real significance is AC ammeter they read current as flux input. Even an ohmmeter is reads voltage to determine resistance as a function of IR drop

∙ 12y agoAn ammeter can be converted into a voltmeter by connecting a resistor in series with it. This works best if the ammeter is a very sensitive ammeter, such as in the micro ampere range.
More commonly, a voltmeter (or sensitive ammeter) is converted into an ammeter by placing a small resistor in parallel with it.

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 is instrument specially designed to measure voltage?

How does an ammeter work?
An ammeter is a low voltage voltmeter in parallel with a small resistance resistor. Current flow through the resistor creates a voltage drop across it which is then measured by the voltmeter.
What is the purpose of multimeter in a laboratory?
it can be used as a ammeter, voltmeter and also as a ohmmeter.
Could a voltmeter be used in a wheatstone bridge instead of an ammeter?
Yes, of course.
How do you connect an ammeter and voltmeter?
The voltmeter is connected across the supply and the ammeter is connected in series with the supply.
Voltmeter in series?
No. Voltmeter in parallel. Ammeter in series.
How can you say that ammeter measures current and voltmeter measures voltage?
voltmeter in parallel and ammeter in series of a circuit.
How should a ammeter and voltmeter be connected in circuit?
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
How is voltmeter connected to ammeter?
in series

Can a multimeter be used as substitute of ammeter and voltmeter why?
yes it can read both ac and dc voltage and current .AnswerThe whole point of a multimeter is that it can perform the function of an ammeter, a voltmeter, and an ohmmeter!
What is the calibration of ammeter?
An ammeter should not be used as a voltmeter. An ammeter is a low impedance device that measures the current going through a circuit, often by measuring the small voltage across a known resistance. A voltmeter is a high impedance device that measures the voltage across a circuit. If you were to connect an ammeter as if it were a voltmeter, you would effectively short out the circuit, drastically affecting its operation, and potentially damaging both the circuit and the ammeter.
How is a voltmeter visually different from an ammeter?
They can both be the same superficial size and have the same visual appearance as a "meter" but a voltmeter has its scale marked out in volts and an ammeter has its scale marked out in amps.
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.
