((The power of one lemon))
I. .. Why do we need in this experiment:
A copper wire size 18 smaller size will work but Harder was 18
2 pin steel Kdbos Securities .. And could be replaced with a strip of zinc will work better.
3 for the lemon or two ..
Scissors, 4 wire ..
II .. How to Make Battery: -
1 Cut two inches of bare copper wire cable with scissors.
2 Insert the steel pin (or two inches of cord zinc) and copper wire inside the lemon ..
3 lemon squeeze gently with your hand without it explodes lemon skin so that the turn lemon on the table and pressing it simple only ..
4 wet your tongue with saliva and then near the end of your tongue wet steel and copper wires ..
5 What you feel .. Only feel a tingling on the tip of your tongue and ****llic taste ..
III .. Scientific explanation:
The lemon battery is called the battery voltage which leads to change of the chemical energy transformed into electrical energy .. Battery consists of two different ****ls (steel pin paper and copper wire) .. Where the poles are placed in a liquid, a lemon juice and thereby increase the accumulation of electrons in one end of the electrodes and thus the electron is missing from the other electrode, and when the tongue touching the electrodes close the circle and allows the small electrical current to flow .. And produces a lemon and one about 7 / 10 volts.
What do you lemons??
If you got to Imontin together .. Fbomanc hour run simple electronic advances and about 1.5 volts and use wire to deliver a flexible thin steel wire for the pin Balimouna to copper wire of the other lemon, then a thin wire connecting the other two wires in the lemon to find where the positive and negative poles to run at hand ..
You feel tingling in your tongue and ****llic taste due to the movement of electrons through the saliva on your tongue ..
Note / / do not work the lemon battery to light a small flashlight! The reason for this is that lemon produces only a small stream Earning .. This is not enough to light the lamp and the amount of current flowing through the wire is not sufficient even though the voltage is high enough for the 1.5 volt Blimontin, but the trend is weak.
