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.
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.
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.
An ammeter is always connected in series and a vlotmeter in parallel
That won't work. To convert an ammeter (a galvanometer is a very sensitive type of ammeter) you connect a high value resistor in series with it.
Ammeter is coneccted in series with circuit but Voltmeter is connected in parallel.
No. Voltmeter in parallel. Ammeter in series.
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 voltmeter is connected across the supply and the ammeter is connected in series with the supply.
Connect ammeter in series and voltmeter in parallel to the circuit
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
in series

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.
voltmeter in parallel and ammeter in series of a circuit.

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.
