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

10. Something about Jacob’s Ladder

11. Something about corona

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

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

14. 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 +

18. 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?

19. 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?

20. UC Santa Cruz Tesla Coil at Lowell High School
Tesla’s Power Plant at Niagara

21. UC Santa Cruz Tesla Coil at Lowell High School
Nicola Tesla as a Daredevil?
Long Time Exposure makes it safe!

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

26. 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

27. 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.

28. 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!

29. 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!

Similar to the Tesla Coil, accelerators convert Energy into new forms
Visit the Stanford Linear Accelerator Center (SLAC): Electricity  New particles
SCIPP works on BaBar :
why we are made out of matter
Transformation of Energy
In Space in black holes:
Matter  Light, x-rays, “jets”
SCIPP works on GLAST Mission:
discover the most powerful accelerators in the universe
GLAST
