Compute all parts of given question:
Question: A battery with an Emf of 22.0 V has an internal resistance of r. It is connected to an external resistance of 280 ohms. A current I = 0.0750 A flows out of the battery.
Part A: Determine the internal resistance of the battery and the terminal potential for the battery?
Part B: Determine the power dissipated by the external resistor?
Part C: Determine the power wasted by the internal resistance of the battery?
I need help to find the power dissipated by the external resistor.
