When the switch is open, the potential difference across the terminals of a battery is 20.0 V. When a current of 2.0 A flows, the potential difference across the battery drops to 16 V. (a) If this battery consists of two identical cells in series, what is the electromotive force of each cell? (b) If this battery consists of two identical cells in series, what is the internal resistance of each cell? (c) If this battery consists of two identical cells in parallel, what is the electromotive force of each cell?
