Problem 9: If you try to measure the voltage of a battery with a voltmeter connected in series, as shown in the gure, you won't get a completely accurate measurement because of the internal resistance of the battery. To see how large this effect is, consider trying to measure the terminal voltage of a 3.200 V lithium cell having an internal resistance of 35 Q by placing a 055 kg voltmeter across its terminals.
