Selection of the problem:
I became interested in this idea as we are facing power cuts in our home then and there. The information gathered from this experiment can be utilized by the juice/soup preparing factories to produce electricity for their factory purpose, utilizing the electrical energy produced by the chemical energy got from the fruits and vegetables.
Statement of the problem:
The purpose of the experiment is to find the electrical energy produced in different fruits and vegetables.
Introduction:
Nowadays life has become impossible without electricity. For every walk of life, Electricity has become a basic necessity Right from a small hut to big factories, they (all) are in need of electricity
Though the government takes strenuous efforts to reach the huge demand for electricity, at least on our side we can take efforts to reach our demand partially
In this project we will make a battery in which the acidity inside the fruit or vegetable acts as electrolyte, copper wire as a cathode and zinc wire as an anode. We use multi-meter to measure the quantum of voltage produced.
Formulation of hypothesis:
My hypothesis is that among the selected fruits and vegetables lemon has more electricity generating capacity.
My hypothesis is based on:
1. Salt water battery
2. Lemon battery

Sampling:
v 10 different verities of fruits and vegetables weighing approximately 50gms
v One zinc wire as anode
v One copper wire as cathode
v One multi-meter to check the quantum of voltage
Observation:
Fruit/Vegetable | Day 1 | Day 2 | Day 3 | Day 4 | Day 5 |
Lemon | 0.56 | 0.56 | 0.56 | 0.59 | 0.59 |
Ginger | 0.47 | 0.21 | 0.29 | 0.13 | 0.09 |
Papaya | 0.6 | 0.03 | 0.03 | 0.03 | 0.01 |
Bitter gourd | 0.5 | 0.09 | 0.46 | 0.21 | 0.13 |
Onion | 0.43 | 0.24 | 0.33 | 0.14 | 0.24 |
Tomato | 0.1 | 0.07 | 0.14 | 0.09 | 0.01 |
Orange | 0.5 | 0.02 | 0.01 | 0.01 | 0.01 |
Raw mango | 0.96 | 0.79 | 0.74 | 0.77 | 0.7 |
Banana | 0.43 | 0.05 | 0.03 | 0.03 | 0.02 |
Guava | 0.47 | 0.24 | 0.53 | 0.23 | 0.16 |
Computation of data:
A fruit or vegetable at a time is selected and the voltage in volts is measured and it is repeated five times on the first day. The mean value is found and has been entered in the observation tab-column.
The process was repeated for 5day and the mean values are entered in the tab-column. The result of each and every fruit /vegetable got on a respective day is compared and a conclusion is arrived at.
Testing of hypothesis:
We reject the hypothesis as more voltage is produced in raw mango rather than lemon, orange, onion etc.
Conclusion:
The conclusion of the experiment is that among the randomly selected fruits and vegetables raw mango produced more voltage than other fruits and vegetables.

Authors comment:
It is in my opinion, the voltage produced in any fruit or vegetable will be high based on the acidity (citric acid) present in the fruits/vegetables. And also it will prolong for more days.
