A Tesla coil is a type of resonant transformer that produces high-voltage, low-current electricity, creating spectacular arcs of electricity that can reach several feet in length.
The Science Behind Tesla Coils
The Tesla coil operates on the principle of electromagnetic induction, where an alternating current (AC) flows through a primary coil, generating a magnetic field. This magnetic field then induces an electromotive force (EMF) in a secondary coil, causing it to resonate at a specific frequency. The resonant frequency is typically in the range of 100 kHz to 1 MHz.
The secondary coil, also known as the Tesla coil, is designed to resonate at a specific frequency, which allows it to store energy and amplify the voltage. The high voltage is then discharged through a spark gap, creating the characteristic arcing effect.
