This is crucial for understanding the loss angle of a capacitor, which relates to this phase relationship. Reactance. Reactance is the part of impedance that accounts for the effect of capacitors and inductors in an AC circuit. Unlike resistance, which dissipates energy, reactance stores energy and then releases it back into the circuit at intervals. Reactance can be further

Does capacitor depend on voltage applied across a capacitor?

Here the term C is known as Capacitance. Does the Capacitance depend upon the Voltage applied across the Capacitor? You might answer yes. But it’s not correct. Capacitance only depends upon the physical dimension, dielectric and geometry of Capacitor. In fact the value of Capacitance for a parallel plate Capacitor is given as C = E0ErA / d

Why does a capacitor bend down in a sharp tip?

The curve bends down in a sharp tip. The bottom of the bend is determined by the ESR. In capacitors with relatively high losses, for example electrolytics, the impedance curves reach and are influenced by these losses long before we get to the resonance frequency.
