This document provides information about a report on a Tesla coil. It discusses how Tesla coils work by using resonance to produce high voltage and high frequency alternating current electricity from a lower voltage source. The report includes sections on the introduction, circuit diagram, working principle, applications, advantages and disadvantages of Tesla coils. It concludes that while Tesla coils were once commonly used, their usage has declined but they remain useful in some laboratory and exhibition applications.

2. INTRODUCTION
Tesla invented Tesla coil in 1891. Tesla coil is
primarily used to produce high voltage and
high frequency alternating current electricity.
Tesla coils are capable of producing high
voltages better than artificial means of
producing the same. “It takes the output from
a 120vAC to a several kilovolt transformer and
driver circuit and steps it up to an extremely
high voltage.

5. WORKING PRINCIPAL
This coil has the ability to produce output
voltages up to several million volts based upon
the size of the coil. The Tesla coil works on a
principle to achieve a condition
called resonance. Here, the primary coil emits
huge amounts of current into the secondary
coil to drive the secondary circuit with
maximum energy. frequency.

6. WORKING
The primary coil is connected to the power
source and the secondary coil of a transformer
is coupled loosely to ensure that it resonates.
The capacitor connected in parallel with the
transformer circuit acts as a tuning circuit or
an LC circuit to generate signals at a specific
frequency.

9. APPLICATION
• Aluminum welding
• Cars use these coils for the spark plug ignition
• Created Tesla coil fans, used to generate
artificial lighting, sounds like music Tesla coils
in Entertainment and Education industry are
used as attractions at electronics fairs and
science museums
• High vacuum systems and arc lighters
• Vacuum system leak detectors

10. ADVANTAGES OF TESLA COIL
• Allows uniform distribution of voltage
throughout the winding coils.
• Builds up the voltage at a slow pace and hence
no damage.
• Great performance.
• The use of 3-phase rectifiers for higher powers
can offer tremendous load sharing.

11. DISADVANTAGES OF TESLA COIL
• Tesla coil poses several health hazards due to
high voltage radio frequency emission that
includes skin burn, damage to the nervous
system and heart.
• Involves high costs in buying large DC
smoothing capacitor.
• Construction of circuit consumes much time
as it needs to be perfect to resonate.

12. CONCLUSION
Tesla Coil was once a very popular electrical
device used in many appliances. However, in
the last century slowly but surely usage of
Tesla Coil has reduced drastically. The primary
usage remains in the laboratory and
exhibitions. Few usage of Tesla coil remains in
aerospace industry and ball lighting
experiment. Modified Tesla coils continue to
gain its popularity in cathode ray tubes and
computer power supplies as solid state tesla.
