A Tesla coil is an electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891. [1] It is used to produce high-voltage, low-current, high-frequency alternating-current electricity. [2] [3] Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
English: Circuit diagram of a modern unipolar W:Tesla coil, a spark-excited resonant transformer circuit which produces high frequency high voltage alternating current at low current levels. It was invented by Serbian-American inventor Nikola Tesla in 1891.
This is a modern unipolar version commonly used in entertainment coils, with a toroidal-shaped metal capacitive load E on the high voltage terminal. The primary circuit is shown connected to the primary winding L1 with a variable tap, so that the primary and secondary coils can be adjusted to resonance.

Electrum or Electrum (for Len Lye) (Len Lye being a New Zealand artist), is a 1998 sculpture by Eric Orr and Greg Leyh built around the world's largest Tesla coil. [1] The coil stands 11.5 meters (37 feet) in height, operates at power levels up to 130,000 watts, and produces 3 million volts on its spherical top terminal. [2]

Henry Leroy Transtrom (1885–1951) was an American inventor and showman who worked with high voltage electricity.His book, Electricity at High Pressures and Frequencies, [1] (1913) is still used as a guide for constructing homemade Tesla coils.
