Science: Lemon Power

Hi there! 

This blog is from August 2020.

Today I will be writing about what I did in Science.

Voltage: 

Voltage is the energy that electrons get from a power supply. Voltage is used to make electrical components work, like light bulbs.

Current:

The rate of flow of electrical charge across a point.

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: We rolled it out and released all the acidic charged particles. This allowed them to move around and create a current. The copper and zinc allowed the charged particles to move around, which created a circuit.

Conclusion: This experiment worked. With one lemon, the voltage was 1 volt. With two lemons, the voltage was 2 volts. With 7 lemons the voltage was 2.3 volts, almost the same amount as a triple A battery.
