POTENTIOMETER EXPERIMENT- K12 CBSE PHYSICS #2
POTENTIOMETER EXPERIMENT- INTERNAL RESISTANCE OF A PRIMARY CELL CIRCUIT DIAGRAM : AB- Potentiometer Rh-Rheostat L - Lechlanche cell H.R-High resistance G- Galvanometer R-Known Resistance J- Pencil Jockey positions Bt -Battery Eliminator (3 amps.) K- Plug keys SIMPLE CIRCUIT DIAGRAM EXPERIMENTAL SET UP FORMULA TABULAR COLUMN & OBSERVATION: PROCEDURE: The circuit connections and the experimental set up are made as shown in the previous page. In the open circuit,when resistance is not included, the emf of the cell is deterimned by noting the balncing length. In the closed circuit, when the resistance is included the balncing length is to be noted. The experiment is r epeated fo r different values of R and the readings are tabulated. Using the formula the internal resistance of the given cell can be calculated . RESULT: ...
