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. 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 wasted by the internal resistance of the battery.
