Nikola Tesla Part II

Alright.. here is a nice video summing up what we read in our book last night, you are welcome to watch it on your own.. it is from Brain Pop! Below.. read the answer to find out why he didn't electrocute himself when he had all that power flowing through him!

How did Nikola Tesla Survive 250 000 volts of electricity?

The alternating current flowing through the wire to Tesla was changing directions at a very high frequency (millions of times a second!). Very high frequency currents have a quirk that kept Nikola safe: High frequency currents travel along the outside of objects instead of penentrating through them. So instead of spreading through Nikola's body, the high-frequency current traveled along the surface of his skin. That protected his heart, which can seize up from even small amounts of current! But don't try any of this yourself...
