Measurements and Instrumentation - Engineering

Q1:

A digital voltmeter has a read out range from 0 to 999 counts. If the full scale reading is 9.999 V, the resolution is

A 1 V

B 0.01 V

C 1 mV

D 1 μV

ANS:C - 1 mV

Resolution is the smallest change in the quantity being measured which will cause an observable change in output. In this case it is 1 mV.
