7. UC Santa Cruz Tesla at Happy Valley School 6 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.

10. 9 n Why does Thomas (“Mr. Electricity”) Edison look so grim? n Is it because he preferred DC current?

11. UC Santa Cruz Tesla at Happy Valley School 10 n Why does Mr. Nicola (“Sparky”) Tesla look so dapper? n Is it because he preferred AC current?

12. UC Santa Cruz Tesla at Happy Valley School 11 n Tesla’s Power Plant at Niagara

13. UC Santa Cruz Tesla at Happy Valley School 12 n Let’s get to know the Tesla Coil

14. UC Santa Cruz Tesla at Happy Valley School 13 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

15. UC Santa Cruz Tesla at Happy Valley School 14 Electrical current flows on the OUTSIDE of a metal! In a thunderstorm stay in the car! Ground Visible sparks Invisible current 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
