Discussion
Arrange the events in an electrostatic precipitator in order:
1. A corona discharge forms at the discharge electrode
2. Particles passing through the corona acquire charge
3. The electric field drives charged particles to the collecting plate
4. Rapping dislodges the collected layer into the hopper
Select the correct sequence.
Answer: D
Charging and collection are separate steps performed by the same field, and removal of the collected dust is a third. Rapping too gently leaves an insulating layer and too hard re-entrains the dust, so its timing is a matter of some care.
