Which of the following instruments is 'NOT' a direct reading instrument?
  1. Voltmeter
  2. Ammeter
  3. Electronic balance
  4. Potentiometer

Solution

A potentiometer is not a direct reading instrument. A direct reading instrument is a tool that gives a direct measurement of a quantity. A potentiometer is used to measure electromotive force (e.m.f.) and potential difference (p.d.), but it doesn't give a direct reading. .
