Understanding Capacitive Reactance with Formulas
Capacitors have a special way of opposing alternating current (AC) which is called capacitive reactance. This is like an internal resistance in the capacitor which changes based on the frequency of the electricity flowing through it. Unlike normal resistance which stays the same, no matter how fast the electricity changes (frequency), …
