A resistance is connected to an AC source. If a capacitor is included in the series circuit, will the average power absorbed by the resistance increase or decrease? If an inductor of small inductance is also included in the series circuit, will the average power absorbed increase or decrease further?

Average Power remains the Same.
Explanation:
The average power absorbed by a circuit is the sum of the power stored and the power returned over one complete cycle.
So a circuits average power consumption will be the average of the instantaneous power over one full cycle with the instantaneous power, p defined as the multiplication of the instantaneous voltage, v by the instantaneous current, i.
Note that as the sine function is periodic and continuous, the average power given over all time will be exactly the same as the average power given over a single cycle.
