Lemon Power

Voltage:

Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating light. In brief, voltage = pressure, and it is measured in volts (V).

Current

An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.

Aim:

To create voltage out of a lemon.

Method:

• Roll the lemon out so the inside is liquidy
• Stick a piece of zinc and copper into the lemon
• Connect the lemon up to a voltmeter

Results:

Discussion:

When we rolled the lemon we made the inside liquidy.  We tried it with one lemon then we moved it to a whole bunch of lemons.  When we rolled it we made a whole lot of acidic acid inside the lemon.  This was then converted to a voltage.  When we connected all the lemons which made 2.3 voltage.

Conclusion:

This was fun and I had learnt how lemons have voltage.  This was a fun and different experience.  I would like to do this again and when I do I would want to try it with a different fruit.  To see which fruit has the most voltage. :)
