Question

A battery is an arrangement of

  1. Electro chemical cells
  2. Wires
  3. Metal
  4. Converters

hintHint:

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.
