WebCurrent measures the flow of charges through an area over time. Figure 1 shows a wire with charges q q moving to the left through the wire, which has a cross sectional area A A. Imagine we counted how many charges passed through the cross sectional area in one second. This rate is the current. In alternating current (AC) systems, the movement of electric charge periodically reverses direction. AC is the form of electric power most commonly delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave, though certain applications use alternative waveforms, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. An important goal in these applications is recovery of i…
