Question

The lowest range on a $4\frac{1}{2}$ digit DVM is 10 mV full scale. The resolution of this meter is ______ $\mu V$.

• A. 0.1
• B. 1
• C. 0.01
• D. 10

Answer 1

The correct option is B 1

$Resolution=\frac{V_{FS}}{{10}^n}$
Where, n = Full digits of DVM

$\therefore Resolution=\frac{10mV}{{10}^4}=1\mu V$
