Question
- Why is it important that the electrodes do not touch each other inside the lemon?
![EXPERIMENT : BATTERY FROM CITRUS FRUITS
МЕТНODS
1. Carefully clean your zinc and copper electrodes to remove any dirt or grease (Do
not scrub all of the zinc coating off the galvanized nails).
2. Roll and squeeze the lemons to release the juice and pulp inside.
3. Insert one galvanized nail and one piece of copper coins into each lemon.
4. Connect the ends of one wire to a galvanized nail in one lemon and then to a piece
of copper coins in another lemon. Repeat this procedure with each of the
remaining lemons until all of them are connected. When you are finished, you
should have one nail and one piece of copper coin unattached.
5. Connect the unattached piece of copper (positive) and the unattached nail
(negative) to the LED.
i)
ii)
Gently bend the lead wires of the LED apart from each other.
Connect a lead wire from the copper electrode of the first lemon cell to the
longer lead wire from the LED.
iii)
Connect a lead wire from the zinc electrode of the third cell to the shorter
wire of the LED.
6. Turn on your light and record how long can this battery light up the LED.
7. Repeat all the procedures (Step 1-5) using calamansis and oranges and compare
the results of all the citrus fruits.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbd872186-21de-4635-9ed5-c18f9da4150d%2F2980c661-ea53-49ce-9350-2ddae3477b14%2F400ulrg_processed.png&w=3840&q=75)
