Sinusoidal waveform
Sine wave is one of the most basic elements in AC symbols. It is a periodic waveform, which can be used to represent the change of alternating current. Sine wave can be expressed by mathematical formula: y=Asin(ωt+φ), where a stands for amplitude, ω stands for angular frequency, t stands for time and φ stands for phase difference.
voltage
Voltage is another important element in alternating current symbol. It represents the potential difference in the circuit. Voltage can be represented by the symbol in the symbol of alternating current, generally represented by V. In the symbol of alternating current, voltage can be represented by the amplitude in sine wave.
electric current
Current is another important element in the symbol of alternating current. It represents the size of the electron flow in the circuit. The current can be represented by the symbol in the symbol of alternating current, generally I. In the symbol of alternating current, the current can be represented by the amplitude in sine wave.
frequency
Frequency is another important element in alternating current symbols. It represents the number of periodic changes in a sine wave. In the symbol of alternating current, frequency can be represented by symbol, generally f, and in the symbol of alternating current, frequency can be represented by angular frequency ω in sine wave.
phase position
Phase is another important element in alternating current symbol. It represents the relative position relationship in sine wave. The symbol of alternating current can be used to indicate the phase, which is generally expressed by φ. In the symbol of alternating current, the phase can be expressed as the phase difference in sine wave.
