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

Observation Table

No Fruits and Vegetables Cell Potential ( E°cell)

1. Lemon 0,8 volt

2. Tomatoes 1,2 volt3. Pear 0,6 volt

4. Cucumber 1 volt

5. Apple 0,6 volt

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

Conclussion

Fruits and vegetables can deliver an electric current, because in the fruits and vegetables have ions
