CAPACITORS

                                              capacitors
Next to resistors are the most widely used passive elements in circuits.Capacitors are the devices which can store electric charge.capacitors may be used to build up sufficient electric charge to fire,for example,flash tube or a laser.they are used in tuned circuits,timing circuits, filters,amplifier circuits.they are also used for power factor correction and for starting single phase motors.
