Answer Posted / pramod
if we are using a transmitter there is defenite distance is
specified for it. if we dont have at least 4mA the signals
will be loss for the max. defined distance.
The mA is chosen because it will not make more electrical
hazardness in the field instead of that if micro A is used
loss of signal may occure.
By taking base as 4mA by persentage means 20 mA set as max
value
