Aim
This experiment to know the electrical conduktivity of fruit and vegetables

Materials
1.Fruit or vegetable (grapefruit, lemon,orange,
and radish, etc)
2.Coppers and zinc plates
3.voltmeter
4.Conducing wire
5.Clips
6.sandpapers

Procedur
1. The part inserted in fruits of the copper and
the zinc plate is sandpapered
2. Two incisions to insert the copper and the zinc plate in the fruit are put.
3. The copper and the zinc plate are inserted in the fruit. Two fruit or more connect in series because the battery power isweak in one fruit
4. The voltmeter connects to the conducting wire. It connects reversely, in the voltmeter needle does not move
the electric power strengthens if two fruit electric cell or more connect in series

Answer the following questions
Question 1.
Fruit that has the highest conductivity ?
Answer : tomatoes
Question 2.
Fruit that has the bottommost ?
Answer : pear and apple
Question 3.
Why vegetable and fruit can deliver an electric current ?
Answer : because fruit and vegetable
contain ions
