Specification
DC power line is a kind of wire used for DC power supply. The so-called DC power refers to the current whose size and direction do not change with time, also known as constant current. It is a closed conductive circuit composed of DC power supply and resistance. It is mainly composed of conductor, insulating layer, shielding layer and shelter layer. It is generally used for flashlight, small radio, mobile phone, MP3, electric mosquito racket and other electrical appliances. The DC power line generally has two lines, one is all black, the other is black, and there is a white solid line in the middle, of which the all black line is the negative pole and the other is the positive pole.
What is the difference between AC / DC power cords?
1. The two represent different meanings: AC is actually the English abbreviation of AC power supply, while DC is the English abbreviation of DC power supply.
2. The current direction is different: the AC flows out in two directions and then flows back, and the size is constantly changing. The frequency is used to indicate the speed of the change of the direction of the AC, and the phase is used to indicate the starting time of AC transmission. In fact, direct current has only one direction, that is, the current can only flow from the positive pole to the negative pole.
3. Different uses: the common electric lamps and motors in our life use AC. DC is mainly used in various electronic instruments, electrolysis, electroplating, DC electric drive and so on.
4. Different output voltages: in fact, DC refers to DC power supply. Commonly used voltages are 30V, 6.0V, 90V and 12V, while AC output voltage is only 220V and 380V.
