Q1Physical Quantities and UnitsFree sample

A digital voltmeter with a three-digit display is used to measure the potential difference across a resistor. The manufacturers of the meter state that its accuracy is $\pm 1\%$ and $\pm 1$ digit.
The reading on the voltmeter is $2.05\text{ V}$ .

(a)

For this reading, calculate, to the nearest digit,

(i)

a change of $1\%$ in the voltmeter reading,

change = ______ $\text{V}$

(ii)

the maximum possible value of the potential difference across the resistor.

maximum value = ______ $\text{V}$

(b)

The reading on the voltmeter has high precision. State and explain why the reading may not be accurate.
