These Lemons Power my Calculator

In this video, the Gaz and Chris attempt to power a Casio calculator using lemons. The calculator isn’t working due to lack of batteries, so they create a battery using lemons, zinc, and copper nails as electrodes. The citric acid in the lemons acts as an electrolyte. They demonstrate that one lemon produces about 0.9 volts, and since the calculator needs around 3 volts, they connect three lemons in series to increase the voltage. After reaching 2.7 volts, they replace the original battery setup with the lemon circuit, successfully powering the calculator. The video explains basic electrical principles like series connections and how the electrodes interact with the electrolyte to generate voltage. They also experiment with cutting a lemon in half, discussing whether this would reduce the voltage, and surprisingly, it doesn’t halve it as expected. The demonstration offers a fun, educational way to explore alternative power sources using common household items like lemons. These videos are designed to help both college lectures and learners studying electrical science and principles. 00:00 - Make electrical science fun 00:22 - Voltage required 00:45 - Nails in lemons 01:34 - Dad jokes 02:15 - Series or parallel 02:51 - Jump leads 03:20 - Check the voltage 03:49 - Will it work? 04:08 - Maths 04:46 - Half a lemon #scienceandtechnology #electricalinstallation #makinglearningfun
