In DC circuits, there is no conception of inductive and capacitive reactance. . An electric circuit is a closed loop or pathway that allows electric charges to flow. In contrast, the instantaneous values of the current, voltage, and resulted power in an AC circuit are continually changing by the supply. The amount of power in circuits at any moment is calledinstantaneous powerand is known by the famous relationship of power equals amps times volts (P = VI). In DC circuits, the voltages and currents are constant and do not vary with time as there is no sinusoidal waveform function related to the supply. Alternating Current Circuits or AC circuits are simply circuits powered by an Alternating Source, either current or voltage.
