Question

Given below is a diagram of electrostatic precipitator. Identify A, B, C and D and select the correct option.

• A. A- Negatively charged wire, B- Negatively charged dust particles, C- Discharge corona, D- collection
• B. A- Negatively charged wire, B- Discharge corona, C- Collection plate, D- Negatively charged dust particles
• C. A- Positively charged wire, B- Positively charged dust particles, C- Discharge corona, D- Collection plate
• D. A-Positively charged wire, B- Discharge corona, C- Collection plate, D- Positively charged dust particles

Answer 1

Answer: (B)

A- Negatively charged wire, B- Discharge corona, C- Collection plate, D- Negatively charged dust particles

The electrostatic precipitator is used to remove air pollution caused by the factories.

So, the correct option is 'A- Negatively charged wire, B- Discharge corona, C- Collection plate, D- Negatively charged dust particles'
