AC Voltage: Definition and Characteristics
In the realm of alternating current, the concept of AC voltage is fundamental. AC voltage, unlike DC voltage, exhibits a sinusoidal waveform, periodically reverses its polarity. Mathematically, an AC voltage, denoted as v(t), can be represented as v(t) = Vpeak * sin(ωt). Here, Vpeak signifies the peak voltage, measured in volts, representing the maximum amplitude of the AC voltage. The term ω represents the angular frequency, quantified in radians per second, dictating how rapidly the AC voltage oscillates. This angular frequency is related to the physical frequency, f, measured in hertz, through the equation ω = 2πf, with f indicating the number of cycles completed per second. Time, represented by t, is measured in seconds.
