In circuit A, a resistor of resistance R is connected across the terminals of a battery with no internal resistance. In circuit B, an identical resistor is connected across a battery which is identical to the battery in the other circuit, except it has internal resistance r. 75.0% less power is dissipated in the resistor in circuit B than the resistor in circuit A. Determine the ratio r/R. Remember to express the answer with three significant digits.

A car battery has an emf of 12.0 V and an internal resistance of 0.20 Ω. While the car is running, the resistance of the rest of the car (the “load” resistance) is 1.00 Ω. What is the current through the battery? What is the terminal voltage of the battery? What is the power delivered to the rest of the car? What is the power dissipated as heat by the internal resistance 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,...
