Vedclass · Answer

(D) An electrostatic precipitator is a device used to remove particulate matter from industrial exhaust.$1$. It consists of electrode wires maintained at several thousand volts,which produce a corona that releases electrons.$2$. These electrons attach to dust particles,giving them a net negative charge.$3$. The collecting plates are grounded and attract the charged dust particles.$4$. The velocity of air between the plates must be low enough to allow the dust to fall,not high,as high velocity would prevent the particles from settling on the plates.Therefore,option $D$ is the incorrect statement.

Choose the incorrect sentence regarding an electrostatic precipitator.
