Electronics. The impedance in an AC (alternating current) circuit is a measure of how much the circuit impedes (hinders) the flow of current through it. The impedance is related to the voltage and the current by the formula V IZ. If a circuit has a current of (0.5 2.0i) amps and an impedance of (0.4 3.0i) ohms, find the voltage.
