Code Number: 5N20.40
Demo Title: Tesla Coil
Condition: Excellent
Principle: High Frequency Tuned Coils
Area of Study: Electricity & Magnetism
Equipment:
Geissler Tubes, Table Top Tesla Coil with Sphere and Pointed Tip Discharge Heads, and Neon and Fluorescent Tubes.
Procedure:
The Welch Tesla Coil Demonstrator has a oil filled capacitor.
CAUTION: Do not tip the capacitor as this will spill oil. Dielectric oil can be used to replaced any that is lost.
6 inch sparks are easily obtained with this unit.
The table top Tesla coil will give 4 to 6 inch sparks quite easily as well as light the variety of fluorescent and neon tubes. You may light the Geissler tubes with both of these coils but you must regulate the output intensity of the large coil so as not to burn out the tube.
