Normally we use batteries as an alternative to electricity. Electricity in potato is generated by the chemical reaction through electrolyte and electrodes. The starchy juices inside the potatoes are what makes the potato a battery. In the next section, learn how to make your own potato battery and know the working principles clearly.
Potato Battery Experiment
The potato also known as the king of vegetables is an electrochemical cell that produces electricity from the chemicals found within it. Let us perform the potato battery experiment listed here to understand how it does so.
Material Required
- Two fresh potato
- Zinc Electrode
- Copper Electrode
- Alligator clips
- A Digital clock
Procedure
- Insert zinc and copper electrodes into the potatoes.
- Use alligator clips to connect electrodes to the digital clock.
- Now, you can see the current passing through the wires and activating the digital clock.
Observation
You can use a digital multimeter to measure the voltage of the current flow from the potatoes. On average, a digital multimeter shows 1.2 volts of electricity between the electrodes. During these experiments the result varies, it is recommended to measure for at least five times and get the average result. Now, you have created the electricity by using a potato battery. However, the main challenge is to produce electricity in a larger amount for a longer time.
