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 Model S The Tesla Model S is a full-sized all-electric five-door, luxury liftback, produced by Tesla, Inc., and introduced on 22 June 2012.[13] It scored a perfect 5.0 NHTSA automobile safety rating.[14] The EPA official range for the 2017 Model S 100D,[15] which is equipped with a 100 kWh (360 MJ) battery pack, is 335 miles (539 km), higher than any other electric car.[16] The EPA rated the 2017 90D Model S's energy consumption at 200.9 watt-hours per kilometer (32.33 kWh/100 mi or 20.09 kWh/100 km) for a combined fuel economy of 104 miles per gallon gasoline equivalent (2.26 L/100 km or 125 mpg‑imp).[17] In 2016, Tesla updated the design of the Model S to closely match that of the Model X. As of August 2017[update], the following versions are available: 75, 75D, 100D and P100D.[18]
