A battery with E = 12.0 V and internal resistance r=1.2Ω is connected to two 8.5-kΩ resistors in series. An ammeter of internal resistance 0.30 Ωmeasures the current, and at the same time a voltmeter with internal resistance 17 kΩ measures the voltage across one of the 8.5-kΩ resistors in the circuit. What does the ammeter read? What does the voltmeter read? What is the % "error" from the current without meters? What is the % "error" from the voltage...

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,...
