The correct answer is: Capacitive reactance is more when capacitance is more and frequency of supply is more.
Capacitive reactance is the opposition to the flow of alternating current (AC) in a capacitor. It is measured in ohms (Ω). The formula for capacitive reactance is $X_C = \dfrac{1}{2\pi fC}$, where $f$ is the frequency of the AC current in hertz (Hz) and $C$ is the capacitance in farads (F).
As you can see from the formula, capacitive reactance is inversely proportional to frequency. This means that as the frequency of the AC current increases, the capacitive reactance decreases. Conversely, as the frequency of the AC current decreases, the capacitive reactance increases.
The capacitance of a capacitor is also a factor in determining its capacitive reactance. The larger the capacitance, the greater the capacitive reactance. This is because a larger capacitor stores more charge, which creates a larger electric field. The electric field opposes the flow of current, which is why a larger capacitor has a higher capacitive reactance.
In conclusion, capacitive reactance is more when capacitance is more and frequency of supply is more.
