The Correct Option is A
Solution and Explanation
Concept:
In AC circuits, a capacitor opposes the flow of alternating current. This opposition is called capacitive reactance.
Step 1: Capacitive reactance is denoted by: \[ X_C \]
Step 2: It is given by: \[ X_C=\frac{1}{2\pi fC} \]
Step 3: It decreases with increase in frequency and capacitance. Therefore: \[ \boxed{\text{Capacitive reactance}} \]
Step 1: Capacitive reactance is denoted by: \[ X_C \]
Step 2: It is given by: \[ X_C=\frac{1}{2\pi fC} \]
Step 3: It decreases with increase in frequency and capacitance. Therefore: \[ \boxed{\text{Capacitive reactance}} \]
