A charger is a power source that provides a source of power for tools. It is an indispensable tool in our daily life. Chargers such as razors, mobile phones, computers, etc. require chargers, but chargers generally have many parameters. AC And DC are two of them, so what does AC and DC written on the charger mean?

1. What does AC mean?

AC stands for "Alternating Current", which is also called "Alternating Current", or "AC" for short. The current whose intensity and direction change periodically with time is called alternating current, or AC for short. It is alternating current that the current direction changes periodically with time. The alternating current commonly used in China is usually 50Hz. The electricity used by our common electric lamps and electric motors is AC. In practice, alternating current is represented by the symbol "~".

2. What does DC mean?

DC stands for "direct current", also known as "constant current". Constant current is a type of direct current, which is a direct current that has the same size and direction. Constant current means that the size (high and low voltage) and direction (positive and negative) do not change with time (relative range), such as dry batteries. Direct current is a unidirectional flow or movement of charge, usually electrons. The current density changes over time, but usually the direction of movement is the same at all times. As an adjective, DC can be used as a reference voltage (its polarity never changes).

What does AC and DC written on the charger mean? Just share it here. In fact, the meaning of AC and DC is well understood, which means AC and DC. In addition to understanding the meaning of these letters when using the charger, how to use the charger correctly is also very important, because if it is used improperly, it will most likely damage the charger and even cause a safety accident. We Must not be ignored.
