​Which of the following statements is/are true of a battery?
1) A battery is a group of galvanic cells connected in series.
2) A battery is a group of galvanic cells connected in parallel.
3) The potentials of all individual cells in a battery add to give the total battery potential.
4) A battery is a source of alternating current.

Quizplus · Accepted Answer

1) A battery is typically a group of galvanic cells that are connected in series (not in parallel), so statement 1 is true.
2) This statement is false because batteries are typically connected in series, not in parallel.
3) This statement is true because potential differences add when cells are connected in series. Therefore, the total battery potential is equal to the sum of the potentials of each individual cell.
4) Batteries are a source of direct current (DC), not alternating current (AC), so this statement is false.
