UC Santa Cruz Tesla at Happy Valley School Program n Jacob's Ladder n Intro on lightning n Corona n Zorro’s Revenge n Tesla and the Tesla Coil n Lighting Fighting n Lights with no wires n Jumping Jacks Thanks to our host n Mr. Mc. Griff (Principal) 2

UC Santa Cruz Tesla at Happy Valley School Before the show begins there are two concepts we must understand n n Lightning The Faraday Cage 3

UC Santa Cruz Tesla at Happy Valley School The Faraday Cage + Why aren't air planes in grave danger being so close to the clouds and all? Answer: They form a Faraday Cage i. e. , they are surrounded by metal; if you are surrounded by metal you are safe the electricity flows around the outside – + + + + – – – + + + Safest place during a lightning storm is in a plane or car 5 because it is a Faraday Cage

UC Santa Cruz Tesla at Happy Valley School 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. 6

UC Santa Cruz Tesla at Happy Valley School SAFETY FIRST! n n n Distance at least 20 ft. Computers, Gameboys, CD players, telephones to the back of the room – unplugged, switched off! Hearing aids off, pacemakers out of room n Normally you can't see, hear or smell electricity, but the Tesla Coil makes • Bright sparks • Loud crackling noise • The air smell bad (Ozone) 1 Million Volts! DANGER BRACE YOURSELF! 7

UC Santa Cruz Tesla at Happy Valley School n Why does Thomas (“Mr. Electricity”) Edison look so grim? n Is it because he preferred DC current? 9

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

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

UC Santa Cruz Tesla at Happy Valley School Principle of the Tesla Coil Ask your teachers about details! 1 million volt Voltage starts at 120 ends up at 1 million! Resonance circuit 14, 000 Transformer volt 120 volt Outlet 13

UC Santa Cruz Tesla at Happy Valley School The armored suit is safe! n It's a Faraday Cage – no electric field allowed inside Invisible current Visible sparks Ground Electrical current flows on the OUTSIDE of a metal! 14 In a thunderstorm stay in the car!
