Zinc Sheet Copper Sheet Electrode Assembly Material

Precautions:

Model: Fruit Battery

Pay attention to the distinction between positive and negative:
In the experiment, the more active metal zinc undergoes an oxidation reaction, so the zinc sheet is the negative electrode and the less active metal copper at the other end is the positive electrode. Light-emitting diodes (LED lights) also have positive and negative poles.

Pay attention to the test environment:
The light emitted by the LED can be very dark due to the strength of the current, so the experiment can be moved to a relatively dark environment.

Pay attention to the connection method:
In the experiment, the two different pieces of metal must be a certain distance apart and must not touch each other. Two pieces of metal on a wire cannot be placed in the same fruit.
One end of the alligator clip is connected to a copper piece of one fruit and the other end is connected to a zinc piece of another fruit; the two alligator clips connected to the diode must not touch each other.
