What is the peak current in a AC circuit with a 50 ohm resistor, 3.3 mH inductor, and a480 nF capacitor in series. If the AC source has a peak emf of 5.0V, then what is the peakcurrent at 3000 Hz?At what frequency do you get the largest potential difference across the resistor? And what isthis potential difference?

Inductors are fundamental components in electronics and electrical circuits. They are passive devices that store energy in the form of a magnetic field when crossed by an electric current. Inductors consist of a wire wound around a core, often made of iron or another ferromagnetic material. The storage of magnetic energy in inductors is expressed in terms of inductance, measured in henries (H). What is the value of inductive reactance (XL​) in ΩΩ, exhibited by the inductor in the circuit below?
