Noun
Tesla coil (plural Tesla coils)
A type of resonant transformer circuit used to produce high-voltage, low-current, high-frequency alternating-current electricity.

Capacitive 'loading' by the streamers tends to lower the resonant frequency of a Tesla coil operating under full power. Source: Internet
Practical aspects of design High voltage production A large Tesla coil of more modern design often operates at very high peak power levels, up to many megawatts (millions of watts This is equivalent to hundreds of thousands of horsepower ). Source: Internet
Experienced Tesla coil builders almost exclusively use the top circuit, often augmenting it with low pass filters (resistor and capacitor (RC) networks) between the supply transformer and spark gap to help protect the supply transformer. Source: Internet
In a spark gap Tesla coil, the primary-to-secondary energy transfer process happens repetitively at typical pulsing rates of 50–500 times per second, depending on the frequency of the input line voltage. Source: Internet
