Why we using 250ohm resistance during lab calibration and why not using in field in one plz define deeply???
Answer / vibhash kumar(voith)
Because our maximum electronic components working in the range of 1 to 5 VDC.250 omhs is suitable for the both 1 to 5 V and 4 to 20 MA.through the omhs law.if we will take 4mA it will for 1vdc and 20 mA for 5 vdc( V= IR).we are not using in field because AI 250 mA already contains.so we have no need in field.
