UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Three things to understand: n Electrical Current n Lightning n The Faraday Cage
UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Lightning Jacob’s Ladder Corona Tesla Sparks are all related. Principle:Air is made of very small bodies called “molecules”. When they are broken apart, they become charged and can conduct a current like an electrical wire. If there is a large current, it heats up the air and makes light (like in your toaster!). Electricity in Air

UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz The Faraday Cage Why aren't air planes in grave danger being so close to the clouds and away from safe ground? –– – – – – – –– – – – – 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

UC Santa Cruz Tesla at Freedom SCIPP UC Santa Cruz We heard a lot about conserving Power (turn off lamps, Air conditioners, ….) Power is brought to your neighborhood on high voltage lines on high voltage lines and a transformer brings it down to 120V We heard a lot about conserving Power (turn off lamps, Air conditioners, ….)
