Solution:
Resolution is the smallest increment an instrument can detect and display.
In the question, it is given that to measure 9.999V number of counts required is 9999.
By the definition of resolution, the value corresponding to one count gives the resolution.
\(\therefore Resolution= {9.999 \over 9999}\)
\(\implies Resolution = 0.001V\: or \: 1mV\)
