A). What is the total rate at which electrical energy is dissipated in the 5.0−Ω resistor?
B). What is the total rate at which electrical energy is dissipated in the 9.0−Ω resistor?
C). What is the power output of the 16.0-V battery?
D). At what rate is electrical energy being converted to other forms in the 8.0-V battery?
The Attempt at a Solution
I can't figure this out at all. For part A, I need the voltage difference and the resistance. How would I find the voltage difference? And does the 5 ohm resistor mean that the resistance is 5 over the resistor? In which case I need to find the voltage drop across the resistor. How do I do this?
