Internal Resistance of Primary Cell Experiment Potentiometer for std 12

Internal Resistance of Primary cell With the help of Potentiometer
EXPERIMENT :- 7
Internal resistance of primary cell
AIM :
To find the internal resistance of a primary cell, by calculation and from a graph, with the help of a potentiometer.
PRINCIPLE :
It works on the principle of potentiometer.
Apparatus:
A potentiometer having a long (~400 cm) resistive wire of uniform cross-section, a battery E of 3 to 4 V, a primary cell ( dry cell or Laclanche cell or a Daniel cell), two rheostats [ 0 – 25 W (Rh1) and 0 – 500 W (Rh2) ], a galvanometer, a R.B.(0 – 50 W), two simple keys and a jockey.
