Electrostatic precipitator in chimneys of factories and hybrid vehicle technology can in curbing air pollution. how? pl give me the answer very fast as u cannn pl

It helps reduce the amount of carbon emissions released into the air
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(slowing down) the flow of gases through the unit.

a device for removing small particles, as of smoke, dust, or oil, from a gas, as air, by passing the gas first through an electrically charged screen that gives a charge to the particles, then between two charged plates where the particles are attracted to one surface.
