Frequency data from this circuit

[nhrock3]

how to know in which frequency the current is maximal in each of those circuits?

what if the frequency range in these circuits
?

Your circuits didn't post, and you didn't show your attempt at the solution yet. Maybe try again?

The maximum current draw will occur at the resonant frequency
http://en.wikipedia.org/wiki/RLC_circuit#Resonance_frequency
but what is the magnitude of that current
?

You still haven't tried to solve this.

A couple of useful facts:

1) in a series circuit, the current does not depend on the order of the components.

2) Resonance is when the reactance of the capacitor cancels out the reactance of the coil.
