Some Advantages Of 12V DC Freezer
Corps
Freezers are the type of refrigerators that are becoming more and more popular in our lives. We have become more and more familiar with them. So do you know what advantages 12V DC Freezer have?
We all know that direct current is a unidirectional flow or movement of electric charge, usually electrons. The current density changes with time, but the direction of movement is usually the same at all times. As an adjective, direct current can be used as a reference voltage (its polarity never changes). When transmitting the same power, the wire used for DC transmission is only 2/3 to 1/2 of that of AC transmission. In cable transmission lines, DC transmission does not produce capacitive current, while AC transmission lines have capacitive currents which cause losses. In DC transmission, the AC systems on both sides do not need to operate synchronously, while AC transmission must operate synchronously. During long-distance AC transmission, the phase of the current will produce a significant phase difference at both ends of the AC transmission system. The loss of DC transmission failure is smaller than that of AC transmission.
However, many home appliances still use AC, but the general mini car freezer uses AC.
