By using this current further drift velocity can be derived and can use to derive the result of Hall Voltage. In the classical view, there are only electrons moving in the same average direction both in the case of electron or hole conductivity. 1. https://apniphysics.com/expt-3hall-effect-experiment-detail-formulation-and-viva-questions-and-demonstration/. 7. The charge carrier hole or electron deviates from the path either upward or downward because of the magnetic force. Now, after making it clear that what components we are using in this experiment, then we start to take the observations. 2 Fig.2 If we move away from O towards the right or left, the intensity of the magnetic field decreases. This phenomenon was discovered in 1879 by … What is the effect of temperature on Hall coefficient of a lightly doped semiconductor? Current consists of the movement of many small charge carriers, typically electrons, holes, ions or all three. 6. 3 thoughts on “ Viva Questions for HALL Effect ” Manish February 8, 2017 Thanks dear they are very useful … Reply Manas Sharma February 8, 2017 Thanks for your comment.
