The Principles and Uses of Electrophorus and Microphone
A device which provides an almost unlimited supply of charge, by induction, was invented by Volta about 1800; it is called an electrophorus. It consists…
Significance of the Hall Effect On SemiConductors
In 1879, Hall found that an e.m.f. is set up transversely or across a current-carrying conductor when a perpendicular magnetic field is applied. This is…
Application, Working Principles and Uses of Potentiometer
Pointer instruments are useless for very accurate measurements: the best of them have an intrinsic error of about 1 percent of full scale. Where greater…
Laboratory and Industrial Uses of Multimeter and Voltmeter
A multimeter instrument is one which is adapted for measuring both current and voltage. It has a shunt R as shown, and a series of…
