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.
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.
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.
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
Ammetre is connected in series because - it contain very low
resistance . And also current is also moves in a straight
line in - to + so ammetre is nessesary for shifting in
straight line or in series.
voltametre is conected in parallel because - it contain
high resistance which can change the value of electric
current. voltametre gives p.d between two points .
if the voltmeter connect in series and ammeter connect in parallel the ammeter is burn because rheostat has resistance and also volt meter has resistance so the ammeter is burn............................ 2010
I am about to face the interview panel of Indian army for
UES(for more details put this address
This is basically a post for engineering job in Indian army?
This is an on campus interview. Kindly help me out with
some tips or the type of questions I am about to face.
Person who dicided to go to weekend trip should not exceed
driving in a day. Average speed of forward journey is 40
Due to traffic in sundays ,in return journey average speed
is 30mph .
