Hey guys, this week I'm here to talk to you about electrical potential. Don't get it mixed up with electrical potential energy. They are not the same. Electrical potential or electrical potential difference is the amount of electrical potential energy per charge. This is measured in joules/coulombs (J/C). This is also know as a volt or voltage. If you look super closely to the poorly taken photo, you can see that this C battery has 1.5 volts. This battery is used to power my radio/speakers. What I learned in physics last class was that because my radio needs eight C batteries and each battery has 1.5 volts, we could replace this with a larger battery that has the same amount of volts. Why would I do this? I would do this because of the fact that the battery has a larger volume, it would have more electrical potential energy. Meaning this would make it last longer and save me more money. Unfortunately, I would have to manually rewire the radio to make the battery fit and even then, the battery will be very bulky and hard to carry around. But it doesn't matter, I probably won't do that anyways. Anyways, I hope you learned something. And join me next week when I'll be teaching you about hopefully something new.
