Question

Which of the following statements are true?

The internal resistance of a battery decreases with decreasing temperature.

A battery is a device that produces electricity by transforming chemical energy into electrical energy.

The potential difference between the terminals of a battery, when no current flows to an external circuit, is referred to as the terminal voltage.

A battery does work on electric charges to bring them to a position of higher electric potential energy so that they can flow through a circuit to lower potential energy.
