why does mA signal preferred for signal transmission?

Answer Posted / 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.
