Question
A battery is an arrangement of
- Electro chemical cells
- Wires
- Metal
- Converters
Hint:
A battery is a device that has active ingredients which contain chemical energy.
The correct answer is: Electro chemical cells
A battery is simply an arrangement of electrochemical cells.
- A battery is a device that has active ingredients i.e. electrochemical cells which contain chemical energy.
- This converts the chemical energy directly to electrical energy through the process of an oxidation-reduction (redox) reaction.
