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. The resulting high-frequency voltage can illuminate fluorescent bulbs several feet away with no electrical wire connection. Eventually, the charge in the secondary capacitor gets so high that it breaks free in a spectacular burst of electric current. The energy sloshes back and forth between the two coils several hundred times per second, and builds up in the secondary coil and capacitor. The voltage zipping through the air between the two coils creates sparks in the spark gap. The massive amount of energy makes the magnetic field collapse quickly, and generates an electric current in the secondary coil. Then, similar to squeezing out a soaked sponge, the current flows out of the capacitor down the primary coil and creates a magnetic field. Eventually, the capacitor builds up so much charge that it breaks down the air resistance in the spark gap. 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. The primary coil's capacitor acts like a sponge and soaks up the charge. The power source is hooked up to the primary coil.
