Discrete capacitors deviate from the ideal capacitor. An ideal capacitor only stores and releases electrical energy, with no dissipation. Capacitor components have losses and parasitic inductive parts. These imperfections in material and construction can have positive implications such as linear frequency and temperature behavior in class 1 ceramic capacitors. Conversely…

9.1.2: Capacitors and Capacitance

Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage (V) across their plates. The capacitance (C) of a capacitor is defined as the ratio of the maximum charge (Q) that can be stored in a capacitor to the applied voltage (V) across its plates.

Understanding Capacitors

Variable capacitor is a capacitor in which capacitance can be adjusted by turning a knob or dial. can be adjusted to store different amounts of electrical charge. These capacitors provide the capacitance values so as to vary between 10 to 500pF.
