INTRODUCTION
In this topic, we are going to show you how a potato can be used the generate the free electric energy working experiments for your science fair project or exhibitions.
What is Electric Energy? How it can be produced?
Electric energy can be generated in electric power plants by burning fossil fuels like oil and coal.
Electric energy can also be produced by burning fuel heats up the water.
Boiling water is converted to steam which is passed through pipes into a turbine.
As the turbine spins due to steam it turns a generator that unbalances charges in nearby atoms and results in the production of the of electricity.
What is Battery and how it works?
Battery works when electrons move in a solution. Batteries have a copper end that is positive and another end that is negative made up of zinc.
Zinc metal gives its electrons to copper and the process stops. However, if we provide electrons with a solution named as an electrolyte, it helps them move to copper with ease and then give electrons a wire in which they can move from the copper back to the zinc.
Hence we can produce a circuit and flowing path of electrical energy. This means electricity is produced or stored as voltage and has a path for that charge to flow as current where as it has another part know as resistance such as light bulb.
How Potato can be used as battery?
With the battery concept, Potato also stored with energy(hence potato can be used as electrolytes) which can be used to light the bulb. Potatoes can be used in parallel or in a series manner to produce the energy to light the electric bulb.
Each potato can generate .5 volts if you boil the potato it generates 10 times of voltage.
If we add 100 potato’s in serial then it can generate 50 V. Now you might scratching the head how many potatoes required to light 220 v bulb
how long does a potato battery last?
Potato battery can last 2 to 3 days or until it becomes bad

Questions & Answers on Potato Battery Making
- Can a potato power a light bulb?
No potato cannot light bulb on its own; we need a battery to power up a light bulb. - Why does a potato generate electricity?
Electricity is generated due to the chemical reaction between copper and zinc electrodes and sulfuric acid in the battery. - How much electricity does a potato produce?
Scientists have discovered that one boiled potato can produce 5 volts of energy.
Conclusions
This model basically helps the students in understanding the battery concepts. Also how potatoes can be used to free energy for your science fair projects
