The pinyin of alternating current is: jiāoliúdiàn, the phonetic notation is: ㄐㄠㄡㄉㄢ, and the part of speech is: the noun structure is: alternating current (upper and lower structure) (left and right structure) (single structure).
What is the specific explanation of alternating current? We will introduce you through the following aspects:
I. Text Description Click here to view the details of the plan.
Alternating current whose direction and intensity change periodically (1). The advantage of this current is that a transformer can be used to change the voltage. At present, the frequency of alternating current used in industry and daily life is fifty times per second.
Second, the citation interpretation
⒈ refers to the current whose magnitude and direction change periodically at any time. The commonly used alternating current in China is 50 Hz sinusoidal alternating current, that is, the current changes periodically 50 times per second according to a sinusoidal waveform. The advantage of alternating current is that the voltage can be changed as needed through the transformer.
Third, the national language dictionary.
A form of electric current. It periodically changes back and forth in two directions, and one cycle per second is one hertz. Its advantage is that the voltage can be changed as needed through the transformer.
Fourthly, online interpretation.
Alternating current (abbreviated as AC) means that the direction of current changes periodically at any time, and the running average value in a period is zero. Unlike direct current, its direction changes with time, and direct current does not change periodically. Usually the waveform is sinusoidal. Alternating current can effectively transmit electricity. But there are actually other waveforms, such as triangle wave and square wave. The commercial power used in life is sine wave alternating current.
