Answer / ashok bhatti
Current does not have any drop during transimission through
electrical wires however the voltage drops as the lengh of
elecrical wire used for transmission increases.
Thats why mA is preffered over mV etc.

Answer / ibrahim s
mA Signal :-
1. Current measures remain same in any point of the signal
transmission line(no loss).
2. Less noise interference.
mV Signal:-
1. Voltage droup occurs(loss).
2. Noise interference is high.
So that mA signal is preferred over mV signal

MA IS PREFFERED THERE IS NO DROP IN CURRENT.SO ONLY MA
IS PREFFERED

Answer / kush kumar
as we know voltage is noise sensitive ..so if transmission
is in the form of voltage then ll loose the original signal
nd at the reciever side ll not get accurate reading ,,but
in d form of current ..its not affected by noise

Answer / r santhosh kumar
most probably mA signal is preffered in signal transmission
because the voltage in the cable may be affected by the
sidewise power cables which are running with this cable
(in the same cable tray).

Answer / shan
mA is the ideal analog signal to be used because it has no
voltage drop. The same current will be recieved even in
100m transmission line.
Voltage signal is much accurate than mA but it is good only
for short range application because of its characteristics.
Prone to noise and voltage drop.

Answer / deepak
ma signal is preffered because current signal does not drop
during transmission through sigal cable as comapred to
volatage signal but sometimes it gets affected by the stray
pickups that can e eliminated by connecting the shielding
at one end.

Answer / vipul joshi mfl
The voltage will drop at the length of the cable but in the
case of mA the current will not drop at the receiver end so
we preferred the current as a signal transmission and for
4-20 mA it is preferred cause the 4 mA is a signal we use as
a zero value if we use 0-12 or 0-20 mA then if any break in
cable was there, we cannot judge.
