Working Principle of Electric Generator | Electrical4U

Oct 28, 2020· When a conductor moves in a magnetic field, an emf is induced across the conductor.This is the only basis on which each and every rotating electric generator works (such as portable generators).. According to Faraday's law of electromagnetic induction, when a conductor links with a changing flux, it will have an induced emf across it.The value of induced emf across the conductor …

Electrostatic precipitator - Wikipedia

An electrostatic precipitator is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit. In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very …
