n ammeter model consists of an ideal ammeter in series with a 20-22 resistor. It is connected with a current source and an unknown esistor Rx as shown in the given figure. The ammeter reading is noted. When a potentiometer R is added and adjusted until the mmeter reading drops to one half its previous reading, then R = 67 2. What is the value of Rx? he value of Rx is 20 92 S2. Ammeter model
