- The circuit is initially powered on, and the transistor (Q1) is in the "on" position. This means that current can pass through the Tesla coil's primary coil. | - The circuit is initially powered on, and the transistor (Q1) is in the "on" position.

- | - A magnetic field forms around the primary coil when current travels through it. This magnetic field causes a voltage to be generated in the secondary coil, which is wrapped around the primary coil. | + | - A magnetic field forms around the primary coil when current travels through it. This magnetic field causes a voltage to be generated in the secondary coil, where primary coil is wrapped around the secondary coil. |
- However, an unusual event occurs when the current in the secondary coil exceeds a particular threshold, often the breakdown current of an LED linked in series. The transistor's base is linked to ground, thus pulling it "down" and causing the transistor to reach a cutoff state. | - However, an unusual event occurs when the current in the secondary coil exceeds a particular threshold, often the breakdown current of an LED linked in series.

- When the transistor reaches cutoff mode, current is no longer conducted through the primary coil. This causes the magnetic field generated by the primary coil to collapse. | - When the transistor reaches cutoff mode, current is no longer conducted through the primary coil.

- A high-voltage flyback voltage is induced in the primary coil as the magnetic field decreases. This flyback voltage discharges into the surrounding air, causing an electric arc or plasma to form. | - A high-voltage flyback voltage is induced in the primary coil as the magnetic field decreases.

- | - The interruption of current flow in the primary coil has an effect on the secondary coil as well. A voltage spike in the secondary coil is caused by the sudden shift in magnetic field, which might result in a high-voltage output. | + | - The interruption of current flow in the primary coil has an effect on the secondary coil as well.

- The process is repeated indefinitely. When the flyback voltage dissipates and the current in the secondary coil falls below the breakdown level of the LED connected in series, the voltage falls below the breakdown level of the LED. This permits the transistor to return to saturation mode, turning it "on" and commencing the magnetic field accumulation. | - The process is repeated indefinitely.
