Question

An electrostatic precipitator is the same as:

a) An air filter that uses activated charcoal
b) A device that uses a magnetic field to remove particles from the air
c) An air cleaner that uses ionization to remove particles
d) A machine that uses ultraviolet light to eliminate pollutants

Answer 1

An electrostatic precipitator is a device that uses ionization to remove particles from the air, by charging them and collecting them on an oppositely charged grid.

Step-by-step explanation:

An electrostatic precipitator is a device that cleans the air by using ionization to remove particles. This process involves airflow passing through grids of opposite charge. The first grid charges the airborne particles, and the second grid attracts and collects them. Large electrostatic precipitators are especially effective and are used industrially to remove over 99% of particles from stack gas emissions, which are typically associated with the burning of coal and oil. These precipitators are not only used in industrial settings but also can be found in home heating and air conditioning systems, where they help remove polluting particles, irritants, and allergens from the air.
