Capacitive reactance is more when_______?
Correct answer: A. capacitance is less and frequency of supply is less
- A. capacitance is less and frequency of supply is less
- B. capacitance is less and frequency of supply is more
- C. capacitance is more and frequency of supply is less
- D. capacitance is more and frequency of supply is more
Explanation
Capacitive reactance is Xc = 1/(2πfC), so it becomes larger when both capacitance and supply frequency are smaller. Option A gives both required conditions.
