Ammeter is connected in the series because it measures the
current which would be flowing in a single series line by a
series of electrons

Voltmeter is connected in parallel because it measures the
potential difference between two terminals(voltage) which
cannot be done when connected in series as ammeter.

Answer / aman dabgotra

The internal impedence of an ammeter is very low. So if it
is connected in parallel with any circuit, the equivalent
resistance of the circuit reduced to almost zero.
On the other hand voltmeter has very high internal
impedence, So if it is placed in series with any device
then that device become almost open circuited.
Thats why these devices are connected in such manner.

Answer / charles

WHEN THE AMMETER IS CONNECTED IN PARLLEL IT WILL BURN
BECAUSE THE INTERNAL IMPEDANCE OF THE AMMETER IS
CONSISDERLY VERY SMALL , BUT IF WE CONNECTED THE VOLTMETER
IN SERIES ,NOTHING WILL HAPPEN BECAUSE ,THE INTERNAL
RESISTANCE OF THE VOLTMETER IS VERY HIGH , IT JUST LIKE A
CONNECTING A HIGH VALU RESISTER PARALLEL TO LINE.

Answer / mohd

The ammeter is connected in the circuit in series because it
has low resistance and the voltage is connected in parallel
because it has high resistance.

Answer / ekta choudhary

Ammeter is used to measure the current flowing through a
circuit element and current is nothing but it is due to a
continuous flow of electrons. We take caution also in
connecting (+) & (-)terminal of ammeter in which electrons
flow from (-)to (+)just opposite to the direction of
current. This is all about for series connection of ammeter
in circuit. If we take reason about parallel connection of
voltmeter across the circuit element then we should know
that it measures the voltage difference between the
required points of circuit element which can only be
measured by connecting it across the circuit element rather
than series connection of it.

Answer / divya

Ammeter is connected in series because it should show the
same current passing through whole circuit.


The potential difference across the ends of resistors may
differ.So to get the poteantial difference across the ends
of the conductor we should connect volt meter in parallel
in the circuit.

Answer / himanshu agrahari

It is always connected in series because it has very low resistance and the current which is in any metal wire have the same resistance as is in ammeter and to get the proper reading of current it should always connected in series

Answer / atinder makkar

The ammeter is not connected in parallel because it will
draw large current and disturb the circuit, right?

Answer / k.paleswararao

ammeter connected in series bcoz it has low resistance
material in low ressistance material the total current
flowing so it measures the total current
voltmeter is high resistance so high resistance low
current high voltage it measure the voltage bet ween two
terminals

Answer / aparna

Ammeter is connected in series b cause it has low resistance and it is used to understand the value of whole circuit not a single bulb or resistor. Voltmeter is connected in parallel because to get the total p.d flowing through the circuit and it has high resistance
