What Are the Most Common Applications for AC Current?
The charged particles, in the circuit of the wire, periodically and alternately change with time according to the magnitude and direction of the value, also known as the analog movement of the electron. Alternating current, also commonly referred to as alternating current. AC current is the opposite of DC current.

- [Example] AC motors use AC currents instead of DC currents, build a large-scale substation, and provide high-power three-phase AC power to the plant.
- For high-voltage transmission transformers, alternating current must be used to generate an alternating magnetic field in order to achieve the high-low voltage conversion process. The main advantages of high-voltage power transmission are: it reduces the cost of power transmission and improves social and economic benefits. The disadvantage is that the cost of safety facilities for high-voltage transmission increases. The utilization rate of AC current is high. Industries, agriculture, light industry and other industries cannot do without the universal application of AC current in practice.
- (The magnitude and direction of the current change with time, so it is called a fluctuating current. For circuit analysis, one of the most important fluctuating currents is a sinusoidal AC current. Its magnitude and direction change periodically with time according to the sine law. (Alternating current is abbreviated as AC or ac, and the instantaneous value of the alternating current should be represented by lowercase i or i ( t ).)
