What is a capacitor
capacitor, usually referred to as 'the ability of its hold charge for capacitance, represented by the letter' C '.
Definition 1: capacitor, just as its name implies, is & lsquo;
Containers of electric & rsquo;
, is a kind of hold charge device.
English name: capacitor.
Capacitor is one of the extensive use of electronic components in electronic equipment, widely used in the circuit in the isolation pass-through, coupling, bypass, filtering, tuning circuit, energy conversion, control, etc.
Definition 2: capacitor, any two insulation and interval of conductor (close to each other
Including the conductor)
Among all constitute a capacitor.
Different capacitance and capacitor.
Capacitance of the basic physical quantities, symbol C, the unit is F (
General formula = Q/C U special formula: parallel plate capacitor plate between the electric field intensity E = U/d, capacitor decided to type C = & epsilon;
Kd with the changing of electronic information technology, digital electronic products renewal speed is faster and faster, with flat screen TV,
LCD and PDP)
, notebook computers, digital cameras and other products of consumer electronics production volume continues to grow, to drive the capacitor industry growth.
