4-20ma response is linear and we can break it into several
groups e.g '4-20' is 16 means 0 = 4ma and full = 20 ma.
half of that is 8 and quater of that is 4 again half of
the quater is 2 and so on . so we can easily calculate all
the neccessary details relating to the signal supply ,...
now why we r not using the 4 -40 ma -- cause difference is
36 here so the quater part of it , is 4.5 and half of the
quater is 2.something so the calculation is complex in such
a case .... also it ll not shows linear responce....
