Introduction:
Making electricity from
chemicals is based on the same scientific principles on which
all modern batteries work. You insert copper and zinc electrodes
in a chemical solution (electrolyte) and produce some
electricity from the chemical reaction between your electrodes
and electrolyte.
In a
potato battery, the electrolyte will be a potato, not a
synthetically made chemical. Potatoes are safe to handle so all
students can try this project safely. |
