As the frequency of an AC circuit increases, the current first increases and then decreases.

As the frequency of an AC circuit increases the current first increases and then decreases. What combination of circuit elements is most likely to comprise the circuit ? (a) Inductor and capacitor (b) Resistor and inductor (c) Resistor and capacitor (d) Resistor inductor and capacitor

(a, d) Compare the given circuit by predicting the variation in their reactances with frequency. So, that then we can decide the elements.,Reactance of an inductor of inductance L is X,L, = 2πvL, where v is the frequency of the AC circuit.
