Learn how to make battery from lemon

Successfully creating battery from a lemons is not easy.

Batteries consist of two different metals suspended in

an acidic solution. Copper and Zinc work well as

the metals and the citric acid content of a lemon will provide

the acidic solution.

Lemon batteris will not be able torun a motor or something

liek that, but it would be able to produce a dom glow from an LED.

What you need? Lemon (fresh, juicy works best),

nail (I used a 2" galvanized common nail) and the penny.

Creating the battery: First insert a penny into a cut

on one side of the lemon.

Push a galvanized nail into the other side of the lemon.

Watch that naild and penny dont touch.

This is a single cell of a battery.

The zinc nail and the copper penny are called electrodes.

The lemon juice is called electrolyte.

All batteries have a "+" and "-" terminal. Electric current is

a flow of atomic particles called electrons. Certain materials ,

called conductors, allow electrons to flow through them.

Most metals (copper, iron) are good conductors of electricity.

Electrons will flow from the "-" electrode of a battery,

through a conductor, towards the "+" electrode of a battery.

Volts (voltage) is a measure of the force moving the electrons.

(High voltage is dangerous!)

Voltmeter tell me that lemon battery is creating a voltage

of 0.906 volts. But thats not enough to light a blub.

To solve this problem we need more lemon batteries

and connect them with

a metal wire from "+" to "-". That would add voltage from each cell.

The two lemon batteries above, combine to produce a voltage

of 1.788 volts. This combination still does not create enough current

to light a small bulb. Note the red wire connecting the batteries

is joined from "+" (penny) to "-" (galvanized nail).

Four lemon batteries create a voltage of 3.50 volts.

Now we should be able to light up a small device like

an LED (Light Emitting Diode).

Note the connecting wires go from "+" to "-" on each battery.

To turn on an LED you must determine the "+" and "-"

connections. If you look closely at the red plastic base

of an LED you will notice a "flat" spot (indicated by arrow above).

The wire that comes out beside the flat spot must connect to the "-"

side of a battery, the other wire to the "+" side.

Important information about LEDs: LEDs are designed to work

at very low voltages (~ 2V) and low currents. They will be damaged

if connected to batteries rated at over 2 volts. LEDs require resistors

to control current when used with batteries rated at over 2 volts.

Lemon batteries produce low current. It is OK to connect an LED to a lemon battery.

In the above image, electrons flow from the "-" (nail) end of our lemon battery

through the LED (making it glow) then back to the "+" (penny) end of the battery.

This is an electronic circuit. The LED glows dimly with this configuration.

Improving your battery.

The quality of the copper and zinc can be a problem

for a battery like this. Pennies in particular are rarely pure copper.

Try substituting a length of 14 gauge copper wire (common house wire)

for the penny. Experiment with different lengths and configurations

of electrodes. Other sources of zinc and copper may

be found in the plumbing supply department of a hardware store.

So I hope this article helps you to learn how to create lemon battery.

شكراً اخي عبدالرحمن

حركات حلوه وخطيره وجااااااري تجربتها في البيت...

Thanks aa.alamery

والله انا مجربها بنفسي

بس لازم الجلب يكون

دايود ضوئي "Led"

شكرا
