    On the Electronics-tutorials website they state:

    Bandwidth of a Series Resonance Circuit
    If the series RLC circuit is driven by a variable frequency at a constant voltage, then the magnitude of the current, I is proportional to the impedance, Z, therefore at resonance the power absorbed by the circuit must be at its maximum value as P = I2Z.

    Shouldn't this be " current, I is INVERSELY proportional to impedance Z?

    sounds right, since a series resonant circuit is at minimum impedance at resonance.

    You mean inversely sounds right?
