    Capacitor is an electronic component that stores electric charge on two conductors isolated from each other. The capacitance of a capacitor depends on the area of the plates and the dielectric material between them, and is measured in Farads. Capacitors can be connected in parallel to increase total capacitance, or in series to decrease total capacitance. Capacitors work by storing electric charge on their plates when a voltage is applied, and can be used as filters, in timing circuits, and other applications where temporary electric charge storage is needed.

    1. Capacitor is an electronic component
    that stores electric charge.

    2. Two conductors isolated


    electrically from each other and
    from their surrounding, forms a
    capacitor .
    Different types of capacitors
    Electrolytic Capacitor.
    Mica Capacitor.
    Paper Capacitor.
    Non-Polarized Capacitor.
     Ceramic Capacitor.
    Capacitance:

    When a capacitor is charged, its plates have charges of equal magnitudes but opposite signs : q+ and
    q-. However, we refer to the charge of a capacitor as being q, the absolute value of these charges on the
    plates.
    The charge q and the potential difference V for a capacitor are proportional to each other:

    The proportionality constant C is called the capacitance of the capacitor. Its value depends only on the
    geometry of the plates and not on their charge or potential difference.

    The SI unit is called the farad (F): 1 farad (1 F)= 1 coulomb per volt =1 C/V.
    Capacitance :-

    The ability of a capacitor to store a charge on its


    conductive plates gives it its Capacitance value.
    Capacitance can also be determined from the dimensions or
    area, A of the plates and the properties of the dielectric
    material between the plates. A measure of the dielectric
    material is given by the permittivity, ( ε ), or the dielectric
    constant. So another way of expressing the capacitance of a
    capacitor is:
    Capacitors in Parallel:
    Capacitors in Series:
    Charging a Capacitor or working of capacitor
    A capacitor is made up of two metallic plates. With a dielectric material (A dielectric
    material is a substance that is a poor conductor of electricity, but an efficient supporter
    of electrostatic fields)  in between the plates.
    When you apply a voltage over the two plates, an electric field is created. Positive
    charge will collect on one plate and negative charge on the other.

    As the plates become oppositely charged, that potential difference increases until it
    equals the potential difference V between the terminals of the battery. With the electric
    field zero, there is no further drive of electrons. The capacitor is then said to be fully
    charged, with a potential difference V and charge q
    Application of capacitor

    • capacitor is used as filter in rectifier circuits for


    smooth dc output.

    • Capacitor is used in high pass and low pass circuits.


    • Capacitors are used in many devices such as tube
    • light ,fans, chargers etc.
    • Capacitor is used in mobile and camera flash etc.
