We offer Study of Hybrid Parameters of A Transistor,the following studies can be carried out with this set-up: Study of h 11 parameter (input impendance parameter). Study of h 22 parameter (output admittance parameter). Study of h 21 parameter (forward current transfer ratio). Study of h 12 parameter (reverse voltage feedback ratio). The experiment

It is noticed that the resistance of the sample changes when the magnetic field is turned on. The phenomenon, called magnetoresistance, is due to the fact that the drift velocity of all carriers is not same. With the magnetic field on; the Hall voltage V is given as: which compensates exactly the Lorentz force for carriers with the average velocity

Hysteresis Loop tracer enables the user to determine accurately various magnetic parameters of ferromagnetic substances, viz. coercivity, retentivity, saturation magnetisation and hysteresis loss. The present set-up can accept the samples of thin wires of different diameters. The demagnetisation effects, different diameters of samples and eddy curr
