The English scientist Henry Cavendish (1731–1810) determined the factors affecting capacitance. The capacitance (C) of a parallel plate capacitor isdirectly proportional to the area (A) of one plate; inversely proportional to the separation (d) between the plates; directly proportional to the dielectric constant (κ, the Greek letter kappa) of the material between the plates

2 天之前· Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
The third character indicates the maximum amount of capacitance change over the part''s temperature range. The spec for --R capacitors (such as X5R and X7R) is ±15%. The capacitance of parts with a code ending in V can actually decrease by as much as 82%! This probably explains why Y5V capacitors are not so popular.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
The following formulas and equations can be used to calculate the capacitance and related quantities of different shapes of capacitors as follow. The capacitance is the amount of charge stored in a capacitor per volt of potential between its plates. Capacitance can be calculated when charge Q & voltage V of the capacitor are known: C = Q/V
An ideal capacitor is characterized by a constant capacitance C, in farads in the SI system of units, defined as the ratio of the positive or negative charge Q on each conductor to the voltage V between them: A capacitance of one farad (F) means that one coulomb of charge on each conductor causes a voltage of one volt across the device.
Real capacitor model that adds an inductance and resistance in series and a conductance in parallel to its capacitance. Its total impedance is: An ideal capacitor only stores and releases electrical energy, without dissipation.
Variable capacitors are made as trimmers, that are typically adjusted only during circuit calibration, and as a device tunable during operation of the electronic instrument. The most common group is the fixed capacitors. Many are named based on the type of dielectric.
The nominal value of the Capacitance, C of a capacitor is the most important of all capacitor characteristics. This value measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF) and is marked onto the body of the capacitor as numbers, letters or coloured bands.
