Problem 10: If you try and measure the voltage of a battery with a
voltmeter connected in series, 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 1.585 V alkaline cell having an internal resistance of 52 2 by placing
a 0.95 k2 voltmeter across its terminals.
