1 Answer

Answer :

i) Resolution: It is the smallest increment in the input which can be detected by the instrument or the smallest measurable input change. 

ii) Drift: The gradual shift in the indication or record of the instrument over an extended period of time, during which the true value of the variable does not change is referred to as drift.
