UC Santa Cruz Tesla Coil at Lowell High School SAFETY FIRST! Normally you can't see, hear or smell electricity, but the Tesla Coil makes Bright sparks Loud crackling noise The air smells bad (Ozone) 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 BRACE YOURSELF! 1 Million Volts! DANGER

Something about corona

UC Santa Cruz Tesla Coil at Lowell High School Before the show begins there are two concepts we must understand Lightning The Faraday Cage

UC Santa Cruz Tesla Coil at Lowell High School How lightning works + – + – +

UC Santa Cruz Tesla Coil at Lowell High School The Faraday Cage + – Why aren't air planes in grave danger being so close to the clouds and all? Safest place during a lightning storm is in a plane or car because it is a Faraday Cage 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 of the metal +

Lowell Physics Student Mystery Knight… Lowell Physics Student in Armor

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

UC Santa Cruz Tesla Coil at Lowell High School Why does Mr. Nicola (“Sparky”) Tesla look so dapper? Is it because he preferred AC current?

UC Santa Cruz Tesla Coil at Lowell High School Let’s get to know the Tesla Coil

UC Santa Cruz Tesla Coil at Lowell High School Resonance circuit 1 million volt Ask your teachers about details! Voltage starts at 120 ends up at 1 million! Transformer 14,000 volt Outlet 120 volt

UC Santa Cruz Tesla Coil at Lowell High School Transformer Power out = Power in Power = Volt  Current Power out Where have you seen this before? Power in Later on in class you will see a Transformer demonstration.

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

UC Santa Cruz Tesla Coil at Lowell High School Resonance circuit Amplitude = Force M (f2natural – f2force) A kick at the right frequency builds up and gets you sky-high!
