  When buying a refrigerator, everyone must have heard of the DC freezer . Let’s learn about AC and DC together today.

  Communication: Think about how we communicate? When a person speaks and everyone listens to it, it is not called communication. It is a speech. Two or more people have questions and answers to each other, and communication is called communication. This is the case with alternating current. It flows out and then back. There are two directions for alternating current, and there is no difference between positive and negative (in fact, it cannot be distinguished, and its polarity can only be said instantaneously)DC: Always, straight flow, never looking back. The direct current flows only from the positive pole to the negative pole, so the direct current has only one direction.

  Since the direction of alternating current is constantly changing (flowing out and flowing back), how many times do you know it will flow back in a second? How many times per second (unit time) is the frequency (everyone knows it), and it is expressed in Hz (Hertz) in electricity. For example, the electricity consumption of lighting in my country is set at 50Hz, which means that the alternating current in the wire will flow out and then flow every second Go back 50 times.

  Many refrigerators use AC power, such as big size freezer , most of it uses AC power.
