1. When a batter, goes "bad", which of the following is most likely to have happened?
A) The voltage was used up.
B) The battery's internal resistance increased.
C) The battery's internal resistance decreased.
D) The voltage was used up as well as the internal resistance decreased.
2. Appliances in the United States arc designed to work on 110-120 volts, whereas appliances in Europe operate on 220-240 volts. What would happen if you triad to use a European electric shaver in the United States?
A) It would probably work as well as it does in Europe, since it is the power rating, not the voltage rating, which matters.
B) It would probably work about as well as it does in Europe, since it is the current rating, not the voltage rating, that matters.
C) It would barely work since the voltage here is too low to push enough current through the device.
D) It would probably overheat and burn up before very long.
