Verified
The precipitator uses a high-voltage DC power supply to provide a set of wires with a positive charge and a set of plates with a _____ charge.
A) negative
B) positive
C) neutral
High-Voltage DC
A system used for the transmission of electrical power over long distances with high voltage in direct current form, reducing power losses and increasing transmission efficiency.
Negative Charge
An electrical charge characterized by the presence of more electrons than protons, resulting in a net decrease in electrical potential.

Final Answer :
A
Explanation :
In a precipitator, the high-voltage DC power supply charges a set of wires positively, and the plates are charged negatively to attract and collect the particles from the air or gas passing through, using the principle of electrostatic attraction.
