Solve the all parts of following question given below:
Question: A 60.0- and a 60.0- resistor are connected in parallel. When this combination is connected across a battery, the current delivered by the battery is 0.187 A. When the 60.0- resistor is disconnected, the current from the battery drops to 0.0966 A.
Part I: Determine the emf of the battery?
Part II: Determine the internal resistance of the battery?
Please provide any help is greatly appreciated!
