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.
The correct answer is: Smoke particles get charged by the precipitator, so they are then attracted to its charged plates.
The correct answer is: Smoke particles are naturally charged, so they are attracted to the charged plates in the precipitators.
In a precipitator, an electric field is applied to remove particles, such as smoke, from a gas stream. The electric field is created by placing plates with a high voltage electrical potential inside the precipitator.
As the gas stream passes through the precipitator, the smoke particles present in the stream become charged due to various mechanisms such as ionization of gas molecules and electrostatic induction. These charged smoke particles are then attracted to the oppositely charged plates in the precipitator.
The electric field causes the charged smoke particles to move towards the grounded plates, where they collect and form a layer. Over time, this layer increases in thickness and eventually falls into a hopper at the bottom of the precipitator. This process effectively removes the smoke particles from the gas stream.
Therefore, the successful use of a precipitator relies on the application of electric fields to charge and attract smoke particles towards the plates, allowing for their removal from the gas stream.
