The power socket is divided into AC socket and DC socket. What's the difference between them? What's the specific details? Here's a detailed introduction.
AC in power socket refers to alternating current, DC refers to direct current. AC is usually marked 250V10A, indicating that the maximum 250V voltage and 10A current are allowed. In practical application, it is better not to exceed the voltage and current values in order to avoid fire and other dangers. AC power socket is first defined as strong electricity and alternating current. Used in the field of household appliances and electricians. Generally, sockets can be regarded as DC direct current, such as chargers, sockets for other electronic products, connectors, etc. Electronic applications are wider.
AC power socket AC is alternating current, while the public power supply is DC power. AC power socket is widely used in home and industry. It is superior to ordinary power outlet in power, volume and components, and represents the development direction of voltage stabilized power supply. The life of AC power socket is more than 10,000 times of that of ordinary power supply. In the temperature range of - 40 ~+85, the electric strength is 2,000 volts. The 250 universal AC mark v10a indicates that the allowable voltage is up to 250 volts and the current is 10 A. In practical application, the voltage and current value should not exceed this value in order to avoid fire and other dangers.
So we often see such terms as socket AC10A, so what does that mean? In fact, socket can bring a maximum current of 10 A, can bring a maximum power of 10 A*220 V=2200W, beyond this power, wire will heat, and even short circuit will cause fire.
Why should AC and DC be used differently? First of all, we should know that the direction or size of DC current are invariable, and the AC current will change with time. Both of them are widely used in society. The typical application of DC is battery. With batteries, many household appliances, these can participate in the operation. And AC is more common in our life. Our household electricity use AC. There is a typical advantage of AC, that is, convenience. As we all know, we use both small change and fire wire. For example, 220 V household electricity, the potential of zero line is 0 V. Because of different time, fire wire generates corresponding potential of addition and subtraction to zero line. When adding current is one direction, when subtracting current is another aspect, which forms alternating transformation direction. The current, therefore, is called alternating current. Another advantage of AC is that it can be boosted or lowered. It has the advantages of using transmission, higher efficiency of generating electricity, simpler and more convenient equipment for production. Compared with DC, it has no obvious advantages in these aspects. And it is also very convenient to convert to DC. If DC is used to transfer current, it will be much more troublesome.
