Because the ammeter measures the current flowing THROUGH the wire, but
the voltmeter only measures the potential difference between two points.
No. Voltmeter in parallel. Ammeter in series.
voltmeter in parallel and ammeter in series of a 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
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.
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.
Place in parallel anywhere in the circuit. One lead goes to the hot, the other to the neutral.
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.
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.
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.
A voltmeter does not measure current, it measures voltage in units named volts. An ammeter measures current in units named amperes or amps in common shorthand. A voltmeter is connected in parallel to the circuit being measured, whereas an ammeter is connected in series with the circuit being measured.
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.
