The Tesla coil will function with one drive circuit but [Richard] notes that it is more stable with two. The build doesn’t stop with the solid-state circuitry, though.

To investigate the electrical realm of high-frequency and high-voltage, Tesla invented an apparatus that pushed the limits of electrical understanding. None of the circuit's typical components ...

The Tesla coil requires one more thing: a capacitor to store charge and fire it all in one huge spark. The circuit of the coil contains a capacitor and a small hole called a spark gap.

The secondary coil with thousands of turns is the cylinder standing up vertically, separated from the lower coil by air. (Photo: Wikimedia) The Tesla coil requires one more thing: a capacitor to store ...

Engineering students at the University of South Florida have built a massive Tesla coils that shoots 15-foot-long sparks to the tune of Super Mario Brothers.

Tesla’s Tower would be far more powerful than a small, experimental coil tested in a lab. Figure 1 shows the massive tower that was to be a new universal telecommunications system spanning the ...

Using a powerful electric force emitted by a Tesla coil, scientists at Rice University have made carbon nanotubes self-assemble to form a circuit linking two LEDs and then used the energy from ...

The Tesla coil was designed by Nikola Tesla in 1891 as a way to transmit electrical energy without wires, and the researchers used this property in combination with Teslaphoresis to create self ...

The Tesla secret lies in the use of an air-core transformer driven by a high-frequency AC source with the transformer primary and secondary tuned to resonate at a particular frequency. In examining ...

The primary side of a Tesla coil is usually a handful of turns of thick wire to handle the current without melting. This build runs at two or three amps, giving a primary power of around 150 Watts.
