4000w Pure Sine Wave Off Grid Inverter

GI series :4000w pure sine wave off grid inverter

     In 1885, Hertz experimented with an oscillating coil with two windings, primary and secondary, and accidentally found that when a pulse current was input into the primary coil, an electric spark would be generated in the middle of the slit at both ends of the secondary winding, and Hertz immediately thought of it. , which may be an electromagnetic resonance phenomenon. Since the oscillating current of the primary coil can excite the spark of the secondary coil, it can generate an oscillating displacement current in the adjacent medium, and this displacement current will in turn affect the intensity of the spark in the secondary winding.

     In 1886, Hertz designed a ring-shaped wire C with a gap of a linear open oscillator as an inductor and placed it near the linear oscillator AB. When a pulse current is input to AB and a spark is generated in the gap, the gap of C will be generated. Sparks are also produced. This is actually the generation, propagation and reception of electromagnetic waves.

     Prove the consistency of electromagnetic waves and light waves: In March 1888, Hertz measured the speed of electromagnetic waves, and introduced the measurement method in the paper "On Electromagnetic Waves in Air and Their Reflections": Hertz used standing waves formed by electromagnetic waves to measure adjacent The distance between the two nodes (half wavelength), combined with the frequency of the vibrator, calculates the speed of the electromagnetic wave. He nailed a sheet of lead to one wall of a large room to reflect electromagnetic waves to form standing waves.
