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
1 V
0.01 V
1 mV
1 μV
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.

9.999/999 = 0.01.

Ans B.

9.999V/999 = 0.01V?
