Calculating Capacitance and Capacitive Reactance

A capacitor is a device that can store electric charge on its conductive plates. The amount of charge (Q) that a capacitor can store depends on the voltage difference between its plates. When a capacitor is connected to an alternating current (AC) circuit, its capacitance affects how well it can store and release charge as […]
