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
Answer: Option
Explanation:
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.

o/p = (step size) * (decimal value).
Here,
o/p is 9.999V for decimal value of 999 .
i.e: 9.999 = (step size) * (999).
=> step size = 0.01.
Now, resolution = (step size) / (full scale reading),
=> (0.01)/(9.999) = 1mV.
