When you connect an unknown resistor across the terminals of a 1.50V AAA battery having negligible internal resistance, you measure a current of 18.3mA flowing through it.

What is the resistance of this resistor?

If you now place the resistor across the terminals of a 12.9V car battery having no internal resistance, how much current will flow?

You now put the resistor across the terminals of an unknown battery of negligible internal resistance and measure a current of 0.459A flowing through it. What is the potential difference across the terminals of the battery?

A real battery is not just an emf. We can model a real 1.5 V battery as a 1.5 V emf in series with a resistor known as the "internal resistance", as shown in the figure(Figure 1) . A typical battery has 1.0 Ω internal resistance due to imperfections that limit current through the battery. When there's no current through the battery, and thus no voltage drop across the internal resistance, the potential difference between its terminals is 1.5 V,...
