Step-by-Step Procedure

  1. 1

    Prepare the PVC pipe as the base for the coil.

  2. 2

    Wrap the copper wire around the PVC pipe to create the primary coil.

  3. 3

    Attach the secondary coil on top of the primary coil using electrical tape.

  4. 4

    Connect the neon transformer to the base.

  5. 5

    Create a terminal cap from aluminum foil and attach it on top.

  6. 6

    Plug in the transformer and turn it on.

  7. 7

    Observe and document the electrical discharges produced.

  8. 8

    Ensure to follow safety precautions throughout.

Expected Results

The Tesla coil should produce notable electrical arcs that demonstrate high-voltage electricity. The size and consistency of the discharges will depend on the quality of the coil construction.

Variables

Independent Variable

number of wire turns in the coils

Dependent Variable

length of electrical discharges

Controlled Variables

power supply voltage, coil height, environmental humidity

Safety Notes

Always wear safety goggles and avoid direct contact with the coil when powered on to prevent electric shock.

Presentation Tips

  • Use a video to showcase the Tesla coil in action.

  • Include a clear explanation of how the coil works.

  • Create diagrams to illustrate the electrical flow.

  • Provide safety information for working with high voltage.
