15,000 Volts

What happens when you connect cables carrying 15,000 volts of electricity to a large plank of wood. Melanie Hoff, a student at Pratt Institute, found out.

What's even more amazing is in the second half of the video when she reverses the voltage.

She didn't reverse the voltage, she reversed the film!!!!!!!!!!!!!

...those sure are light weight cables for 15,000 volts ! How can that work?

P=I^2 R; so the heat dissipated in a cable is proportional to /current/ squared. As long as the current flowing is small, the cables don't need to be too thick. And very high voltages tend to go with low currents.
