where does a tesla coil get its power
Tesla coil A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents.[10][15][16][17][18][19] Tesla's original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer. More sophisticated designs use transistor or thyristor[15] switches or vacuum tube electronic oscillators to drive the resonant transformer.
Tesla, Inc. The Tesla Roadster (2008) was the first production automobile to use lithium-ion battery cells and the first production EV with a range greater than 200 mi (320 km) per charge.[15] Between 2008 and March 2012, Tesla sold more than 2,250 Roadsters in 31 countries.[16][17][18] Tesla stopped taking orders for the Roadster in the U.S. market in August 2011.[19]
