δ is the angle between the capacitor''s impedance vector and the negative reactive axis. DF is the Dissipation Factor (sometimes expressed as a percentage). ESR stands for Equivalent Series Resistance X C is the capacitive reactance Capacitive Reactance . Reactance is used to compute amplitude and phase changes of sinusoidal current.

Capacitance in AC Circuits results in a time-dependent current which is shifted in phase by 90 o with respect to the supply voltage producing an effect known as capacitive reactance. When capacitors are connected …

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 […]
Capacitors and Capacitive Reactance Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.44 . The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance.

Capacitive reactance (Capacitor Impedance) is also a force which resists the flow of an alternating current. Because the capacitive reactance causes a 90-degree phase displacement, the total resistance to an ac current must be the vector sum of X C and R. ...
Key learnings: Reactance Definition: Reactance is defined as the opposition to current flow in a circuit element due to inductance and capacitance.; Inductive Reactance: Inductive reactance, caused by inductors, stores energy in a magnetic field and makes current lag behind voltage.; Capacitive Reactance: Capacitive reactance, …
Capacitors and Capacitive Reactance. Consider the capacitor connected directly to an AC voltage source as shown in Figure 23.46. The resistance of a circuit like this can be made so small that it has a negligible effect compared with the capacitor, and so we can assume negligible resistance. Voltage across the capacitor …
