    MINI TESLA COIL:

    Introduction:
    • A Tesla Coil is a circuit that generates a high
    voltage, high frequency electromagnetic field even
    from a low voltage DC source.

    • Slayer exciter is simplest version of tesla coil as


    slayer exciter requires only some basic
    components(transistor, resistor, a primary coil and
    a secondary coil) and also it is does not produce
    much heat because it consumes less power.
    TOOLS USED:
    1. ENAMELED COPPER WIRE(L=20
    M, D=.3mm).
    2. Transistor – 2N2222A.
    3. RESISTANCE – 2.2K OHM.
    4. KEY.
    5. CELL – 9V.
    6. PVC PIPE (12CM).
    7. CONNECTING WIRE.
    WORKING PRINCIPLE:
    The Tesla coil works with the principleof
    Electromagnetic Induction. According to
    which, when a conductor is placed under a
    varying magnetic field, a small current will
    be induced inside the conductor.
    How does it work:

    1. Turning the circuit on, R drives the base of the


    transistor Q
    2. Q turns on and drives current into the primary of the
    transformer. The current is limited by the limited
    available base current.
    3. The created magnetic field drives the secondary of
    the transformer.
    4. The secondary voltage wants to grows large. But the
    tiny stray capacitance on the output resists the
    change, although very small, against the rise of the
    output end and so in return the voltage on the other
    end of the transformer goes down, pulling the base
    of the transistor low.
    5. Diode D prevents the base voltage to fall more than
    0.7V below ground, which in return pushes the
    output end of the secondary high.
    6. The transistor turns off and so the magnetic field
    starts to reduce.
    7. The base voltage rises again and Q turns on and the
    cycle repeats.

    Circuit diagram:
    Procedure to construct a Tesla
    coil:
    1. Take pvc pipe and winde 300-400 turns of 28G
    copper wire.[Primary coil]
    2. Apply tape at bottom and winde 4-5 turns of 22G
    copper wire [Secondary coil].
    3. Now remove enamel of copper wires at end.
    4. Solder 22k ohm resistor to the base of 2n2222
    transistor.
    5. Solder bottom end wire of primary coil to base.
    6. Solder one end of secondary coil to collector.
    7.Solder Positive terminal of battery clip to Switch and
    negative terminal to emitter pin.
    8. Now solder another end of secondary coil and another
    pin of switch to the free end of 22k resistor.
    9. Leave the top end wire of primary coil free in air.

    Result:
    Whenever we bring a fluorscent bulb close to the secondary
    winding, after switching on the circuit, The bulb glows
    producing high intensity light as bulb glows when supplied ac
    power. It is the transmission of electrical energy from
    power source to electric load, over a distance, without
    usage of wires or cables.
    The key parameter in transmitting power is efficiency.
    Conventional methods of transmitting power don’t have
    high capacity of transmitting energy with less power
    loss.Long range communication is possible which is
    impossible with conventional method, is achieved with
    this technology.

    Conclusion:
    Doing this project we conclude that with the help of this kind
    of technology, wireless power transmission can be made
    possible and this technology will help us in eradicating the
    hazardous uses of electrical wires and
    Huge power losses in transmission. It is envisaged that
    wireless energy would be really accomplished with the
    advantage of easy implementation and cost effective
    i.e., cost of transmission and distribution overhead
    would become less. In the long run, this could reduce
    our society’s dependence on batteries, which are
    currently heavy and expensive.
    WIRES… A BURDEN!!!
    Future Applications:
    Wireless electricity transmission can change the world of
    electricity and electrical engineering. The power loss due to
    transmission lines can be reduced(no I square R loss).
    Less amount of wires would be used in any circuit.
