Impedance: A 120-V rms voltage at 60.0 Hz is applied across an inductor, a capacitor, and a resistor in series. If the peak current in this circuit is 0.8484 A, what is the impedance of this circuit?

Question

Quizplus · Accepted Answer

The impedance of a circuit is given by the formula Z = V/I, where V is the voltage across the circuit and I is the current through the circuit. In this case, the voltage is 120 V and the current is 0.8484 A, so the impedance is Z = 120 V / 0.8484 A = 141 Ω.
