A capacitor consists of a layer of insulating material sandwiched between two metal plates. The capacitance can be calculated using the capacitor dimensions and the permittivity of the insulating material, which this article will examine. The charge quantity stored by a capacitor with a given terminal voltage is its capacitance.
The charge on a capacitor is directly proportional to the applied voltage and the capacitance of the capacitor: QaCE Q a C E The farad1 (F) is the SI unit of capacitance that contains a charge of 1 coulomb when the difference across its terminals is 1 volt.
The charge quantity stored by a capacitor with a given terminal voltage is its capacitance. The capacitance of a capacitor has a definite relationship to the area of the plates and the thickness of the dielectric. Refer to Figure 1 (a) and recall that electrons are attracted to a positive voltage.
The capacitance and the voltage rating can be used to find the so-called capacitor code. The voltage rating is defined as the maximum voltage that a capacitor can withstand. This coding system helps identify and select the appropriate capacitor for electronic circuitry. The capacitor code also allows you to find the capacitance of a capacitor.
