To Provide high current with efficiency and little drop in output voltage, a cell should have
(A) A high voltage
(B) Low internal Resistance
(C) A low Ah rating
(D) All of these
Me myself thinks that its B.
My book states 2 things that make me believe this:
(1). In general, a cell (or battery) provides the most energy when the temperature is high and the discharge schedule, current drain, and final voltage are low.
(2). According to Ohm's law, a current that is flowing through a resistance (either external or internal) results in a voltage drop.
If someone could give me their ideas and help I would be appricietive

You need at least A and B. B to get a low voltage drop and A to get high current. I'm not sure what effect C has. It's been awhile.
After a little more research, C would also apply for the efficiency reason. So D is your answer.

an unexplainable fluid. It is known how to produce it because of its effects but it is still a mystery. In fact all new inventions such as T.V. Radio, Computers etc need electricity to function, but why is not completly understood. Some try to explain electricity through atoms or molecules, but cannot explain its nature.
