Inventions - The Tesla coil: high-voltage resonance for wireless energy
Inventions · 0:45
In 1891, inventor Nikola Tesla designed the Tesla coil, an electrical resonant transformer that produces high-voltage, low-current, and high-frequency alternating current. Tesla built these devices with coupled resonant circuits to explore electrical lighting, phosphorescence, X-ray generation, and the wireless transmission of electrical power. Before modern electronics replaced spark gaps for switching, Tesla coils powered early spark-gap transmitters for wireless telegraphy and found use in medical equipment. Today, they remain popular for educational displays and vacuum leak detection.
