Capacitor and Coil

[A] is a circuit connected in series with a capacitor, a light bulb and an AC power supply. [B] is a circuit connected in series with a coil, a light bulb and an AC power supply. The AC power supply and the light bulb are the same for both A and B. How will the brightness of the bulbs in A and B change, respectively, if we increase the frequency of the AC power supply?

The RMS electrical power value of the AC power supply is constant.
