When you connect an unknown resistor across the terminals of a 1.50 V AAA battery having negligible internal resistance, you measure a current of 19.0 mA flowing through it. You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of 0.393 AA flowing through it. What is the potential difference across the terminals of the battery?
