WebFeb 20, 2024 · Figure 21.5. 2 :The potentiometer, a null measurement device. (a) A voltage source connected to a long wire resistor passes a constant current I through it. (b) An unknown emf (labeled script E x in the figure) is connected as shown, and the point of contact along R is adjusted until the galvanometer reads zero. WebAmmeter Working Principle: The working principle of an ammeter depends on the current flowing along with its resistance. Very little impedance is used inside the ammeter as it must drop the least amount of voltage attached to it. The ammeter is connected to the series of circuits as the current in the series circuit is the same.
