We can see from the equation for capacitance that the units of capacitance are C/V, which are called farads (F) after the nineteenth-century English physicist Michael Faraday. The equation C = Q / V C = Q / V makes sense: A parallel-plate capacitor (like the one shown in Figure 18.28 ) the size of a football field could hold a lot of charge without requiring too …
In basic electrostatics, the formula for the capacitance of parallel-plate capacitors is derived, for the case that the spacing between the electrodes is very small compared to the length or width of the plates. However, when the separation is wide, the formula for very small separation does not provide accurate results. In our previously …

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. In other words, …
The SI unit of capacitance is the farad (F), named after Michael Faraday. Dimension: M-1 ·L-2 ·T 4 ·I 2. An important practical application of this concept is associated with a device called a capacitor. A capacitor is an elementary linear electronic component designed to add capacitance to an electrical circuit.

According to this equation, the energy held by a capacitor is proportional to both its capacitance and the voltage''s square.
