Why Ammeter is connected in series with circuit & Volt meter is connected in parallel with circuit?
An ammeter is connected in series with the circuit because the purpose of the ammeter is to measure the current through the circuit. Since the ammeter is a low impedance device, connecting it in parallel with the circuit would cause a short circuit, damaging the ammeter and/or the circuit.
1) It should be connected in series, so that maximum current can pass through it, for accurate measurement of current.
2) its resistance is very low, if it is connected in parallel in a circuit, it will by the current, and current can not be measured accurately.
if you do not connect the ammeter in series you will shunt the load, basically excluding the resistive element of the circuit.

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.

Deleteits best answer thanks
ReplyDeletewhy the ammeter will short circuit if it is connected in parallel ?
ReplyDeleteit gets damaged
Deletethe ammeter has negligible resistance.... when connected in parallel, it will get a large amount of potential difference ( because in parallel voltage is consant) .... since current is directly proportional to V and inversely proportional to R... thus a large amount of current will flow through ammeter... this will cause a short circuit.

ReplyDeleteThe answer is awesome.
ReplyDeleteAmmeter measures value of current flowing in circuit, so current should flow inside ammeter to give proper result. And it has very low resistance to ensure the correct measurement of current in the circuit.
ReplyDeleteIf it is connected in parallel across any load then all current in circuit will choose lower resistive path (i.e ammeter) to cause it's circuit to be damaged. Hence it is used in series.
And Voltmeter has very high resistance to ensure that it's connection do not alter flow of current in the circuit.Now if it is connected in series then no current will be there in the circuit due to it's high resistance. Hence it is connected in parallel to the load across which potential difference is to be measured.
ammeter 101
what happens if we connect a voltmeter and an ammeter in series with a battery
ReplyDeletevery well explained
ReplyDeleteexcellent
ReplyDeleteSo Awesome
ReplyDeleteIs there any change in parallel combination of two resistors when ammeter is used in that parallel combination of two resistors?
ReplyDeletePlz,could u answer?

you said that the ammeter gives the maximum value but current flow in minimum in series
