The DC power supply used by DC Freezer Wholesaler's DC freezer and the AC power supply used by the AC freezer have two different currents, but they can work in most appliances. We all know that although these two currents are only one word difference, their functions are different. So, what is the difference between these two current directions?

There are two directions for alternating current. It flows out and then flows back. The amplitude is constantly changing (the changing law of the lighting current is sinusoidal). Frequency can indicate the speed of change in AC direction, and phase can indicate the start time of AC transmission. Therefore, in electricity, amplitude, frequency, and phase are called the three elements of alternating current, which is really good. Only when these three factors are mentioned at the same time can the characteristics of alternating current be clearly explained.
