What is Tesla coil :
A Tesla Coil used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, and the transmission of electrical energy with-out wires like that “Wireless Electricity”.
A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents
Required Components For Tesla-Coil Circuit-:
(i)One Pieces PVC Pipe (Length-8.5cm & Diameter-2cm)
(ii)One Pieces 2N2222A Transistor
(iii)9V Battery & Battery Cap
(iv)One Pieces Switch
(v)2G Copper Wire
(vi) Wood Base
It’s consists of two parts:
- A primary coil and secondary coil, each with its own capacitor. The two coils and capacitors are connected by a spark gap, a gap of air between two electrodes that generates the spark of electricity. An outside source hooked up to a transformer powers the whole system. Essentially, the Tesla coil is two open electric circuits connected to a spark gap.
- Making coil, needs a high-voltage power source. A regular power source fed through a transformer can produce a current with the necessary power (at least thousands of volts).
In this case, a transformer can convert the low voltage of main power into the high voltage.
How to make Tesla Coil
- Step 1
At first we have to winding the copper wire around the PVC pipe, leave ½ cm of the both end of the pvc pipe.
- Step 2
When the copper wire winding is complete, after that We have to installed all the components on the wood base.
- Step 3
we connect the all components by the wire.
First of all we connect to ‘+ve’ terminal of the 9V battery with switch one point by the wire. And the other point of the switch is connected to one point of inductor (Primary Winding), other point of the inductor is connected to transistor collector(C) point. Base(B) terminal of the transistor is connected to the 22KΩ resistor, other terminal of the resistor connect to other point of switch. Emitter(E) terminal of the transistor is connected‘-ve’ terminal of the 9V battery. After that lower most terminal of the winding around of pvc pipe is connected to between the Circuit Diagram, junction of base and resister.
Tesla-Coil First Inventor:
A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891.It is used to produce high-voltage, low-current, high frequency alternating-current electricity.
