Dc crompton potentiometer

OBJECT: To measure low resistance using Crompton potentiometer. Theory: -There are two types of potentiometer. Galvanometer and Ballistic Galvanometer.

S dwell period to allow the contactor arcs and motor emf to decay – the setting potentiometers are also read at this time. This enables DC to be injected for the time and voltage as set on the potentiometers.
