Question
Batteries are always labeled with their emf; for instance, an AA
flashlight battery is labeled “1.5 volts.” Would it also be appropriate to
put a label on batteries stating how much current they provide? Why or
why not?

In order for the three lights to be bright enough to be seen in daylight, each of the three RL = 50 N lights must dissipate P = the 3 lights are connected in parallel (see the drawing), and the open circuit voltage of the battery (that is, the voltage when there is no current) is Vo = 110 volts. What is the maximum internal battery resistance R; allowable given that each lamp must dissipate 220 watts? 220 watts.

- Your flashlight is getting dimmer and dimmer, so you assume the batteries are nearly dead. They are “D” cells producing 1.5 volts. You take the batteries out and test them with a voltmeter. The meter reveals the batteries have nearly 1.5 volts of potential. Are the batteries dead or is something else going on? Discuss how you can tell whether the batteries are dead, and how you would test the flashlight to see whether there is some internal problem. Is it an either-or proposition?
