Determine the capacitive reactance (Xc) of a capacitor at a given frequency. Vital for AC circuit analysis, filter design, and understanding signal attenuation.
Yes. Capacitors allow high-frequency signals to pass more easily. As frequency goes up, reactance goes down.
It's key for designing high-pass and low-pass filters, blocking DC current while passing AC signals, and impedance matching.
Xc = 1 / (2πfC)
