Discussion
Given below are two statements. One labelled as Assertion (A) and the other labelled as Reason (R).
Assertion (A) : Electrostatic precipitators (ESPs) can be harmful if not operated properly.
Reason (R) : Corona discharge in ESPs produces ozone.
Choose the correct answer :
Answer: A
Both statements are true and the reason explains the assertion. Electrostatic precipitators ionise the gas by corona discharge, and the discharge produces ozone, which is harmful, so an ESP that is not operated properly can be harmful. The answer is that both are correct and R is the correct explanation of A.
