The correct answer is: C. 100 Ohm or more
A flashlight battery has internal resistance of 1 ohm. For what values of load resistance does the flashlight battery appear stiff?
A stiff battery is one that has a small internal resistance. This means that the battery can provide a lot of current without its voltage dropping too much. A battery with a large internal resistance is
said to be “soft.”The amount of current that a battery can provide is determined by the load resistance. The load resistance is the resistance of the device that is being powered by the battery. The higher the load resistance, the less current the battery will be able to provide.
When the load resistance is 100 ohms or more, the battery will appear stiff. This is because the battery will be able to provide a lot of current without its voltage dropping too much.
Option A is incorrect because 60 ohms is not a high enough load resistance to make the battery appear stiff.
Option B is incorrect because 50 ohms is not a high enough load resistance to make the battery appear stiff.
Option D is incorrect because 10 ohms is not a high enough load resistance to make the battery appear stiff.
Option E is incorrect because there is a correct answer.
