QUESTION 4 In an electrostatic precipitator, particles are removed from air by ionisation. The ons and electron flow ionised particles are diverted towards an earthed plate, build up on the collection plates and are removed from the air stream. The magnitude of the resulting current density reaching the earthed plate is well described by the so-called Warburg law: ITOTAL MARKS: 25] Earthed plate ,, ,, J-0 elsewhere with θ...
