Solve the 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. 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 internal resistance of the battery and the terminal potential for the battery.
