TESLA COIL USING 2N2222 TRANSISTOR

Hey there, in this post we learn how to make Tesla coil using 2N222 transistor .

Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents.Tesla's original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer.

More sophisticated designs use transistor or thyristor switches oscillators to drive the resonant transformer.

Now, I am going to instruct how to make a miniature Tesla coil with less number of components.

Component Required:

• 20 gauge magnetic Copper wire -35 cm

• 22 gauge magnetic Copper wire - 9 m

• PVC Pipe

• Switch -1

• Cardboard sheet

• 2N2222A Transistor - 1

• 22K Ohm Resistor - 1

• 9V Battery and Clip - 1

Circuit Diagram & Circuiting:

Procedure:

• Take pvc pipe and winde 300-400 turns of 28G copper wire.[Primary coil]

• Apply tape at bottom and winde 4-5 turns of 22G copper wire [Secondary coil].

• Now remove enamel of copper wires at end.

• Solder 22k ohm resistor to the base of 2N2222 transistor.

• Solder bottom end wire of primary coil to base.

• Solder one end of secondary coil to collector.

• Solder Positive terminal of battery clip to Switch and negative terminal to emitter pin.

• Now solder another end of secondary coil and another pin of switch to the free end of 22k resistor.

• Leave the top end wire of primary coil free in air.
