11. UC Santa Cruz Tesla at the Santa Cruz County Science Fair Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Principle:Air becomes ionized, and therefore conducts electricity. Lot’s of it, so the current heats up the air, excites the atoms/molecules which emit light.

16. UC Santa Cruz Tesla at the Santa Cruz County Science Fair Voltage starts at 120 ends up at 1 million! Transformer 14,000 volt Outlet 120 volt Resonance circuit 1 million volt Ask your teachers about details! Principle of the Tesla Coil

17. UC Santa Cruz Tesla at the Santa Cruz County Science Fair TransformerTransformer Power out = Power in Power = Volt  Current Power out = Power in Power = Volt  Current Where have you seen this before? Power in Power out

18. UC Santa Cruz Tesla at the Santa Cruz County Science Fair Resonance circuit Amplitude = Force M (f 2 natural – f 2 force ) A kick at the right frequency build up and gets you sky-high!

19. UC Santa Cruz Tesla at the Santa Cruz County Science Fair Electrical current flows on the OUTSIDE of a metal! In a thunderstorm stay in the car! Ground The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside Invisible current Visible sparks
