alleryA battery is a collection of which parts?
ACopper wire loops
BElectrochemical cells
CRubber insulators
DPlastic switches
Answer & Solution
Correct answer: B. Electrochemical cells
1. A battery is a collection of electrochemical cells.
2. A wire, an insulator or switches are not what makes up a battery.
3. So the collection of cells is correct.
