Because the ammeter measures the current flowing THROUGH the wire, but

the voltmeter only measures the potential difference between two points.

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.


Where ammeter and voltmeter are put in circuit?

Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.


How is an ammeter converted to a voltmeter?

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.


How do you connect an ammeter and voltmeter?

To connect an ammeter, you must place it in series with the circuit so that the current flows through the ammeter. To connect a voltmeter, you must place it in parallel with the component you are measuring the voltage across. Make sure to set the ammeter and voltmeter to the proper range before connecting them.


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.


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.


Where must a voltmeter be placed in a 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.


Why is the voltmeter connected in parallel but the ammeter connected in series?

The Voltmeter is used to measure the electrical potential difference between two points... so it's no use to connect it in Series , because the electrical potential difference between two points at the same line is zero ==> the readings will always be zero. The Ammeter is used to measure the electric current in a circuit... so it's no use to connect it in Parallel , because you want to know the current flowing in this wire. note the internal Resistance of the Ammeter is very little and very high for the Voltmeter --> so they will not affect the circuit.
