- Question 5: A 1.5 V D-Battery Suppose you buy a 1.5-volt D-battery at a store. As we have seen, the terminal voltage of this battery will vary depending on the current drawn from it. So just what does the 1.5 volt represent? Before answering this question take a look at a new D-battery. Explain briefly.see imageWhen a 24 resistor is connected across a 12 V battery, a current of 482 mA flows. What is the resulting terminal voltage of the battery?
