Potentiometer can be used as ammeter
WebExplanation: For the calibration of ammeter, potentiometers can be used since it indicates current drawn by the externally connected device. 9. Which of the following devices … A potentiometer is an instrument for measuring voltage or 'potential difference' by comparison of an unknown voltage with a known reference voltage. If a sensitive indicating instrument is used, very little current is drawn from the source of the unknown voltage. Since the reference voltage can be produced from an accurately calibrated voltage divider, a potentiometer can provide high precision in measurement. The method was described by Johann Christian Poggendorff around 1…
