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

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

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

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

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

Electric fields are used to create an electric charge on the plates in the precipitator, which attracts the smoke particles to the plates.
