Hi people, i'm back at it again with a really interesting post. ( The so called TESLA COIL )
How it works
The power source is hooked up to the primary coil. The primary coil's capacitor acts like a sponge and soaks up the charge. The primary coil itself must be able to withstand the massive charge and huge surges of current so the coil is usually made out of copper a good conductor of electricity. Eventually the capacitor builds up so much charge that it breaks down the air resistance in the spark gap. Then similar to squeezing out a soaked sponge the current flows out of the capacitor down the primary coil and creates a magnetic field.
Interesting Huhh - Let's continue.
The massive amount of energy makes the magnetic field collapse quickly and generates an electric current in the secondary coil. The voltage zipping through the air between the two coils creates sparks in the spark gap. The energy sloshes back and forth between the two coils several hundred times per second and builds up in the secondary coil and capacitor. Eventually the charge in the secondary capacitor gets so high that it breaks free in a spectacular burst of electric current.
The resulting high-frequency voltage can illuminate fluorescent bulbs several feet away with no electrical wire connection.
In a perfectly designed Tesla coil when the secondary coil reaches its maximum charge the whole process should start over again and the device should become self-sustaining. In practice however this does not happen. The heated air in the spark gap pulls some of the electricity away from the secondary coil and back into the gap so eventually the Tesla coil will run out of energy. This is why the coil must be hooked up to an outside power supply.
The principle behind the Tesla coil is to achieve a phenomenon called resonance. This happens when the primary coil shoots the current into the secondary coil at just the right time to maximize the energy transferred into the secondary coil. Think of it as timing when to push someone on a swing in order to make it go as high as possible.
Setting up a Tesla coil with an adjustable rotary spark gap gives the operator more control over the voltage of the current it produces. This is how coils can create crazy lightning displays and can even be set up to play music timed to bursts of current.
While the Tesla coil does not have much practical application anymore Tesla’s invention completely revolutionized the way electricity was understood and used. Radios and televisions still use variations of the Tesla coil today.
- Resteem and upvote, if u learned about our maybe "bright" or "dark" future, because they might use it for evil purposes, like they're doing with other of his theories.
