How many characteristics of AC power are there?

AC power is described by five main attributes that determine how energy is delivered and used. The voltage level sets how much electrical energy is available; the current level shows how much energy is flowing. The frequency defines how fast the waveform repeats each second, which matters for devices designed for a specific supply rate. The phase relationship between voltage and current indicates whether current leads or lags the voltage, affecting power factor and how efficiently energy is transferred. The waveform shape describes the form of the alternating signal (typically a sine wave, though actual systems can include harmonics or distortion). While we often use RMS values to express voltage and current for heating and power calculations, these five characteristics together capture the essential way AC power behaves.
