Use the image to answer the question.

Smoke precipitators like the one in the image are used to remove particles from the air.

An illustration shows a smoke precipitator used to remove particles from gases emitted through industrial processes. The smoke with dust particles enters the precipitator at the bottom and passes through the wires with a negative charge. The dust particles collect the negative charges as they flow past the wires. The smoke then moves upward passing through positively charged collector plates. The negatively charged dust particles are attracted to the positively charged plates and stick to them. The hoppers are installed between the wires and positively charged plates. The plates are tapped occasionally to make the dust fall into hoppers.

How are electric fields applied in the successful use of a precipitator?

Responses

Smoke particles are naturally charged, so they are attracted to the charged plates in the precipitators.

Smoke particles are big, so they get filtered by the charged plates in the precipitator.

Smoke particles are heavy, so they precipitate quickly to the hopper in the precipitator.

Smoke particles get charged by the precipitator, so they are then attracted to its charged plates.

Answer 1

Smoke particles get charged by the precipitator, so they are then attracted to its charged plates.
