INTRODUCTION
Tesla coil is considered as a resonant transformer circuit that
is used for the generation of high range voltages, minimal
currents, frequency AC electricity. The output is collected
from 120v AC and transfers to driver circuits and transformers
and then provides a high level of voltage. The delivered
voltage level can be more than 1,000,000 volts and released
in the form of electrical discharges. The distinctive feature of
the tesla coil is its capacity of delivering high electrical fields
or ‘A Tesla coil is a radio frequency oscillator that drives the
air-core double-tuned resonant transformer to produce high
voltages with low currents’.

PRINCIPLE
Tesla coil principle is based on the principle of electromagnetic
induction. As per this principle, when a conductor is kept under
altering magnetic field, there happens induction of current in the
conductor. In the Tesla coil, this conductor is termed a secondary
coil and the generation of altering magnetic field is done by a
primary coil through passing oscillating circuit through it.

APPLICATIONS OF TESLA COIL
Tesla coils or resonant transformers of high frequency and high
potential have been used in many commercial applications; the
only variation being the high voltage is used to produce an effect
other than a spark. Although not all commercial applications for
Tesla coils are still in use, some historical and modern-day
applications are included.
• Spark gap radio transmitters
• Induction and dielectric heating (vacuum tube & Spark gap
types)
• Induction coils (differ only in the transformer core material
being used)
• Medical X-ray devices (typically driven by an induction coil)
• Quack medical devices (violet – ray)
• Ozone generators
• Particle accelerators
• Electrical stage shows & entertainment.

PROCEDURE
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.
