Total opposition to ac current
WebApr 1, 2024 · Impedance is the total passive opposition offered by an electric circuit to the flow of an alternating current (AC). At a basic level, it is a measure of how much a circuit … WebSince this is a series circuit, we know that opposition to electron flow (resistance or impedance) adds to form the total opposition: Now that we know total voltage and total impedance, we can apply Ohm's Law (I=E/Z) to determine total current: Just as with DC, the total current in a series AC circuit is shared equally by all components.
