A single resistor is wired to a battery.

Define the total power dissipated by this circuit as P(initial). What is the Power?
Now, a second identical resistor is wired in series with the first resistor. What is the power, in terms of P(initial), dissipated by this circuit?
The terms have to be in P(initial). No equations and no V or R is part of the answer.
