The Parallel Plate Capacitor. Parallel Plate Capacitors are the type of capacitors which that have an arrangement of electrodes and insulating material (dielectric). The two conducting plates act as electrodes. There is a dielectric between them. This acts as a separator for the plates. The two plates of parallel plate capacitor are of equal dimensions.

The symbols shown in Figure (PageIndex{8}) are circuit representations of various types of capacitors. We generally use the symbol shown in Figure (PageIndex{8a}). The symbol in Figure (PageIndex{8c}) represents a variable-capacitance capacitor. Notice the similarity of these symbols to the symmetry of a parallel-plate capacitor. An ...
The principle of capacitive level measurement is based on change of capacitance. An insulated electrode acts as one plate of capacitor and the tank wall (or reference electrode in a non-metallic vessel) acts as the other plate. The capacitance depends on the fluid level. An empty tank has a lower capacitance while a filled tank has a higher ...

In any capacitor, Q = C x V - more appropriately represented here as V = Q/C. Q represents electrical charge. When a capacitor is charged, there is an imbalance between the quantity of electrons on one plate compared to the other. C represents capacitance, which is the ability of the capacitor to store charge. V is voltage.
