Refrigerators such as 12V DC freezers and Solar DC Freezers have the word DC written. I believe everyone knows about AC and DC when buying electrical appliances, so they are not too unfamiliar. And everyone knows that AC is different from DC, and what we know most is that AC is alternating current and DC is direct current. So apart from that, do you know the difference between these two different currents? Let us take a look at it.
AC can be called neutral and live. DC is called positive and negative.
For AC input, the wiring can be polarized. For DC input, the wiring must distinguish between positive and negative.
AC power parameters need to specify the frequency, such as 50Hz. DC power supplies generally do not have frequency parameters for reference.
The direction of AC current is alternately changed according to the natural period. The direction of DC current flowing from the positive electrode to the negative electrode is constant and does not change.
AC and DC parameters that are often encountered in daily life.
