Nikola Tesla Coloring Page

Nikola Tesla was born in 1856 in a village in what is now Croatia, and he moved to the United States in 1884. He worked out how to send electricity over long distances using alternating current, which switches direction many times a second. His ideas helped power the first big hydroelectric plant at Niagara Falls in 1895.

He also invented the Tesla coil, a machine that makes crackling blue-white sparks, and as a boy he was said to picture an invention completely in his head before he built it. The unit that measures the strength of a magnetic field is named the tesla in his honor.
