Capacitors

A capacitor(the old-fashioned name was condenser) is a device that has two wires sticking out of it and has the property
Q=CV
A capacitor of C farads with V volts across its terminals has q coulombs of stored charge on one plate, and -Q on the other.capacitor is more complicated than a resistor.Capacitors also use in computer technology and mobiles.Information technology is also using capacitors in every tech gadget.Every gadget is using  capacitor in its motherboard. They are also use in industrial unit.Capacitors are the main components of every electronic device.They are known as condenser in electronic field.They can store electric current for a moment .The circuit of AC to DC converter is also use capacitor.
There are many forms of capacitors like veriable capacitor and many others,but veriable capacitors are more efficient and best for using in circuit. There are plates in veriable capacitors.
