Which, if any, of these statements are true? (more than one may be true.) explain your choice or choices.
a. a battery supplies energy to a circuit.
b. a battery is a source of potential difference.
c. the potential difference between the terminals of the battery is always the same.
d. a battery is a source of current.
e. the current leaving the battery is always the same.

The following statement are true

A. A battery supplies energy to a circuit.

   It convert chemical energy to electrical energy by the using of electrodes.

B. A battery is a source of potential difference.

      It contains voltage difference between  terminals.

C. The potential difference between the terminals of the battery is always the same.

Battery is a source of voltage not current.

The current leaving from the battery depends on the resistance.
