AC Domain Description Like DC circuits, the fundamentals of the AC domain are represented in terms of voltage, current, and power. Students can use it to gauge their level of understanding of circuits and to reflect on what still needs to be understood. II. However, for an AC circuit with reactive elements, we have to assess the consumed power differently. On the other hand, In a parallel circuit, the phasor sum of the flowing currents in each element is equal to the supply current (IS). The most common application for resistance in a circuit is the light bulb. As the instantaneous power is continually varying with the sinusoid function over time, it is hard to measure.
