Suppose that a certain battery produces a voltage of 1.55V without a load connected (open circuit) and a current of 750 mA when shorted. According to these specifications, if we were to model this as an ideal voltage source in series with a source resistance, what should the source voltage and internal resistance be? Justify your answer.
