Follow these simple steps to create a potato battery that can light up an led previous next leds just need a tiny bit of electricity to turn on – something you can produce with a potato, a coin and a nail.
How the potato clock works a potato battery is an electrochemical battery, otherwise known as an electrochemical cell an electrochemical cell is a cell in which chemical energy is converted to electric energy by a spontaneous electron transfer in the case of the potato, the zinc in the nail reacts with the copper wire.
Data, graph and results conclusion test sweet potato russet potato red potato one thing that was very difficult was getting the zinc and copper electrodes in the potato skins in the bar graph it shows the voltage amps for each potato for all three trails. Then, add a third wire to the zinc nail in the second potato always remember to connect the copper (positive) end of the potato (battery) to the zinc (negative) end of the next potato (see figure 2) figure 2 activity setup to create a potato battery to power an led clock.
