An electrostatic precipitator (ESP) 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. "Frederick Cottrell invented the "electrostatic precipitator", which removes pollutants from smoke. Cottrell was born on January 10,1877,in Oakland, California, the son of Henry and Cynthia Cottrell. His ingenuity and interest in the applied sciences were demonstrated early on. please mark as brainlist answer you guy

Answer:
Smoke is a colloidal solution of solid particles such as carbon , arsenic compounds , dust etc . in air .
The smoke before it comes out from the chimney , is led through a chamber containing plates having a charge opposite to that carried by smoke particles .
The particles on coming in contact with these plates lose their charge and get precipitated .
The particles then settle down on the floor of the chamber .
The precipitator is called the Cottrell Smoke Precipitator
