The working principle of the AC potentiometer is same as that drydsale the DC potentiometer, i. What is AC Potentiometer? Definition, Types & Applications – Circuit Globe In order to operate the galvanometer at its maximum sensitivity, provision is made to short the protective resistance when near the balance conditions. Measurements of Self Reactant of a Coil - The standard reactance is placed in series with the coil whose reactance is to be measured. There are two step-down transformers T 1 and T 2 which isolate potentiometer from the line and give an earthed screens protection between the winding. The working principle of the AC potentiometer is same as that of the DC potentiometer, i.e., the unknown voltage is determined by Polar Type Potentiometer. Posts about polar type ac potentiometer written by Pragnarongali. potentiometer, not only the magnitudes but phases as well DRYSDALE POLAR TYPE AC. Its principle is same as a But in an a.c.
