Ionisation potential employed in the industrial electrostatic precipitator is of the order of_______________?
Correct answer: A. 30 to 70 kV DC
- A. 30 to 70 kV DC
- B. 30 to 70 kV AC
- C. 230 V AC
- D. 230 V DC
Explanation
Industrial electrostatic precipitators use a high-voltage direct-current field, typically around 30 to 70 kV, to charge particles and drive them toward collecting plates. AC at ordinary supply voltage cannot produce the required sustained ionising field.
