It's too complicated to explain, so here is a screenshot of the circuit:

Given the information in the picture, I need to determine the power delivered to resistor 2. I just want a push in the right direction, so don't worry about solving it for me.

I know all of the formulas that I need. I just need to know how to work with the circuit shown in the picture.

Power is I squared R. R1 and R2 are in series, so call that R3 or whatever and redraw the diagram with R3 instead of R1 and R2 in series. Then it is clear that R3 is in parallel with the 90. Call that combination R4 and redraw the diagram again. Then it is clear that R4 is in series with the 20 and the battery. Calculate all the voltages and currents, then use I squared R for the resistor of interest.

Use the formula H=VIT where V is the voltage, I is the current and T is the time for which the current flows.
