The potential difference between the terminals of a battery is 12V when measured directly using a voltmeter. When the battery is connected to a load of 240?, the reading of the voltmeter becomes 9.6V. What is the internal resistance of the battery? What load resistance should be used so the battery delivers the most power to it? What is this maximum power?
