PHWhy does a capacitor allow more current at higher frequency? 🤔
Capacitive reactance decreases as frequency increases because the capacitor gets less time to charge and discharge in each cycle. As a result, the opposition to AC reduces and current increases.
Key formula:
Xc = 1 / (2 × pi × f × C)
This concept is very important for AC circuits, resonance, and LCR circuit problems.
