Types of capacitors: Capacitors are divided into two mechanical categories. Fixed capacitors: A fixed capacitor is one that holds a specific quantity of electric charge (capacitance) that cannot be adjusted at any time. Their …
4.6: Capacitors and Capacitance
The main difference is that polarized capacitors can only be used in one direction in a circuit while non-polarized capacitors can be used in either direction. Polarized capacitors must also be connected with the correct polarity; otherwise they won''t function properly and may even cause damage to other components.
A variable capacitor is a type of capacitor that allows for adjustment of its capacitance within a certain range. It consists of two sets of pole plates, with one set being fixed (stator) and the other set movable (rotor). The …

Unpolarised capacitors are ideal for use in both voltage directions. Different Capacitor Types Capacitors are categorised into two mechanical groups: fixed and variable. Fixed capacitors consist of a fixed …
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.
