Digital voltmeters often have a choice of ranges. The ranges indicated on a typical voltmeter

Digital voltmeters often have a choice of ranges. The ranges indicated on a typical voltmeter are 0-3, 0-30, 0-300, and 0-3000 AC volts. The output is represented with four significant digits. Determine the following

(a) Resolution uncertainty for each range (in V).

(b) If it has an accuracy of ±2% of full range for each range, determine the absolute uncertainty of measurement in each case.

(c) Determine the relative (percent of reading) uncertainly if, for a measurement of 25 volts, the ranges 30, 300, or 3000 were used.
