Set 2 Cuộn Dây Tesla Arc U47 Cho Ảo Thuật

Tesla coil is a transformer that works according to the principle of resonance (resonant transformer)
It can generate high temperature and high pressure plasma, and can ignite, wirelessly transmit electricity, and illuminate fluorescent lamps; It has a wonderful arc and can be used in many interesting and very interesting scientific experiments
Easy to install, efficient and beautiful
Tesla Coil (Tesla Coil): It is a transformer that uses the principle of resonance operation. In 1891, the American Serbian scientist Nikola Tesla was mainly used to produce ultra-high voltage but low current and high frequency AC power. The Tesla coil consists of two (sometimes three) coupled resonance circuits.
Tesla coils are difficult to define, and Nikola Tesla tried a large number of various coil configurations. Tesla uses these coils for innovative experiments, such as electrical lighting, fluorescence spectrum, X-rays, high-frequency AC current phenomena, electrotherapy and wireless power transmission, and transmission and reception of radio signals. This Tesla coil is classified as a lock.
The resonant coil of the frequency loop introduces the induced current of the secondary coil 2 into the primary oscillation loop, so that the oscillation frequency of the primary loop is locked to the resonance frequency of the secondary coil, thereby maintaining resonance. LED2 is a power indicator, and LED1 is a clamping diode, which does not emit light normally. If transistor Q2 is damaged, LED1 will light up. The audio signal is used to ulate the oscillation frequency. When the audio signal is input, the audio signal voltage changes the primary oscillation frequency, resonance occurs in the secondary coil, and the sound is restored. Voltage input can be from 9-30V, the higher the voltage, the longer the arc, the louder the sound, when the voltage is higher than 15, pay attention to heat dissipation. Audio signals can be connected to mobile phones, MP3s, computers, etc. Tesla coil can light neon lamps, energy-saving lamps, strobe lamps, and cigarette lighters
