In a potentiometer circuit cell of emf 1.5
WebThis cell is wired as shown in the schematic of figure 2, and the DPDT switchmoved to connect it in the circuit in place of the standard cell. The expected Emf value will be around 1.5 volts, so the potentiometer should be initially set using the 1.5 V coil. Briefly depress the contact key, and note the amount and direction of the deflection. http://classes.oc.edu/PhysicsLab/POTENTIO.htm
