The capacitive reactance of a capacitor is _____ proportional to frequency.
A) directly
B) inversely
Capacitive Reactance
The opposition to change in voltage across a capacitor, inversely proportional to the frequency of the applied AC signal and the capacitor's capacitance.
Frequency
The number of times a periodic event repeats in a given time unit, often used to describe the rate at which alternating current cycles, measured in hertz (Hz).
- Identify the relationship between frequency variations and capacitive reactance alterations.

Final Answer :
B
Explanation :
The capacitive reactance of a capacitor is inversely proportional to the frequency, following the formula XC=12πfCX_C = \frac{1}{2\pi fC}XC=2πfC1 , where XCX_CXC is the capacitive reactance, fff is the frequency, and CCC is the capacitance.
