A battery with internal resistance (a) You short-circuit a 9 volt battery by connecting a short wire from one end of the battery to the other end. If the current in the short circuit is measured to be 19 amperes, what is the internal resistance of the battery? (b) What is the power generated by the battery? (c) How much energy is dissipated in the internal resistance every second? (Remember that one watt is joule per second.)

Why is the following situation impossible? A technician is testing a circuit that contains a resistance R. He realizes that a better design for the circuit would include a resistance 73R rather than R. He has three additional resistors, each with resistance R. By combining these additional resistors in a certain combination that is then placed in series with the original resistor, he achieves the desired resistance.
