What are the hazards of 380V AC electric shock?
Alternatingcurrent: the concept of alternating current: at any time, the magnitude and direction of alternating current change periodically, and the current whose average value is equal to zero in a period is called alternating current, or AC for short. Nikola tesla (1856- 1943) invented the alternator early. 1882, shortly after Edison invented direct current (DC), he invented alternating current (AC), made the world's first alternator, and founded multiphase transmission technology. Sinusoidal alternating current is the most widely used, and other non-sinusoidal alternating current can generally be converted into the superposition of sinusoidal alternating current after mathematical treatment. Sinusoidal current (also called harmonic current) is a harmonic function of time. When the closed coil rotates at a uniform speed in the magnetic field, alternating current with periodic changes in size and direction is generated in the coil. The general frequency of alternating current used now is 50Hz. Our common lamps, motors, etc. They all use alternating current. Actually, alternating current is represented by the symbol ~.
