The difference between AC and DC in power outlets

The AC in the power socket refers to alternating current, and DC refers to direct current. Generally, AC is marked with 250V10A, and the marking allows the maximum voltage of 250V and current of 10A. In practical applications, it is best not to exceed the value of voltage and current to avoid fire and other dangers. First of all, the AC power socket is clearly strong and alternating current. Used in the field of household appliances and electrical engineering. General sockets can be regarded as DC direct current, such as chargers, sockets for other electronic products, connectors, etc. Wider electronic applications.

 

The AC of the AC power socket is alternating current, and the public power source is direct current. AC power sockets are widely used in homes and industries. It is superior to ordinary power sockets in terms of power, volume, components, etc., and represents the development direction of regulated power supplies. The service life of AC power sockets is more than 10,000 times that of ordinary ones. In the temperature range of -40 to +85, the electric strength or 2000 volts, the 250 general AC mark v10a, indicates that the allowable voltage is up to 250 volts, and the current is 10a. In practical applications, the voltage and current values ​​should not exceed this value to avoid fire and other hazards.

So we often see terms like this, such as socket AC10A. So what does this mean? In fact, sockets can carry appliances with a maximum current of 10A, and they can carry appliances with a maximum power of 10A*220V=2200W. Power, the wire will heat up, and in severe cases, it will even be short-circuited and cause a fire.

 

 

Why should alternating current and direct current be used separately? First of all, it is necessary to know that the direction or magnitude of the current of the direct current is constant, while the current of the alternating current will change differently with time. The application of both in society is very common, and the typical application of direct current is the battery. With batteries, many household appliances can participate in operation. Moreover, alternating current is even more common in our lives. Our households use alternating current. The amount of alternating current has a typical advantage, that is, convenience. Everyone knows that the electricity we use has two strands of change and live wire. Take household 220V electricity, the potential of the neutral wire is 0V. The live wire generates the corresponding potential of addition and subtraction to the neutral wire because of the different time. When the current is added, It is one direction, and when it is subtracted, the current is another aspect. In this way, a current that alternately changes directions is formed, so it is called alternating current. Another advantage of AC power is that it can be boosted or stepped down, and can be used for transmission. The efficiency of power generation is higher, and the production equipment is simpler and more convenient. Compared with DC power, there is no obvious advantage in these aspects. And it is very convenient to convert to direct current, if direct current to alternating current is much more troublesome.
