A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...
Ugreen (绿联) is a Chinese consumer electronics brand owned by Ugreen Group Ltd and based in Shenzhen, Guangdong. [2] [3] The brand and company was established by Zhang Qingsen in 2012, and specialises in USB hardware such as cables and AC adapters, as well as other categories of consumer electronics such as audio equipment and mobile accessories.

The capacitance of a capacitor is one farad when one coulomb of charge changes the potential between the plates by one volt. [1] [2] Equally, one farad can be described as the capacitance which stores a one-coulomb charge across a potential difference of one volt. [3] The relationship between capacitance, charge, and potential difference is linear.
A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...
For brevity, the notation omits to always specify the unit (ohm or farad) explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors, [nb 1] the case used (uppercase letters are typically used for resistors, lowercase letters for capacitors), [nb 2] a part's appearance, and the context.
