USES OF POTENTIOMETER Uses of potentiometer – Measurement of emf of cell- Let , E is the emf of driver cell and , E1 is the emf of cell to be measured Here potential gradient K= [ {E / (R+r)} r]/l . Let l1 is the length of the wire from […]
POTENTIOMETER THIS TOPIC EXPLAIN ABOUT THE POTENTIOMETER Potentiometer – An instrument used to measure accurately the EMF or potential difference is called potentiometer. Principle– Its working based on the principle that the potential drop across a conductor is directly proportional to the length of the conductor , if constant current passes through the conductor having […]
