Series and Parallel Circuits

Series and Parallel Circuits

Hi. It’s Mr. Andersen and today I’m going to be talking about series and parallel circuits. These are a couple of different circuit diagrams. Remember this stands for a battery and each of those stand for a resistor. And so this would be a series circuit. Remember it’s a closed circuit, so there’s a loop…

Electrical experiments with plants that count and communicate | Greg Gage

I’m a neuroscientist, and I’m the co-founder of Backyard Brains, and our mission is to train the next generation of neuroscientists by taking graduate-level neuroscience research equipment and making it available for kids in middle schools and high schools. And so when we go into the classroom, one way to get them thinking about the…

The Truth about Hydrogen

The Truth about Hydrogen

This episode of Real Engineering is brought to you by Skillshare, home to over twenty thousand classes that could teach you a new life skill. As the world grapples to eliminate fossil fuels from our energy diet, electric cars have seen an incredible boom over the past few years. Last year, over one million electric…

Are My Electronics Making Me Sick?

Are My Electronics Making Me Sick?

[♩INTRO] If you’re watching this episode of SciShow, you’re definitely near an electronic device. And that’s something that around 1-5% of people would say makes them feel nauseated, dizzy, itchy, and otherwise pretty terrible. They’re convinced they have what some call Wifi Syndrome: that their bodies react strongly to the electromagnetic radiation given off by…

Diamond Nuclear Batteries Are Forever… Sort Of

Diamond Nuclear Batteries Are Forever… Sort Of

Since the early 1900s, researchers have been working on ways to turn radioactive material into an electric current that lasts.. for decades. Yeah, that’s right. We’re talking about nuclear batteries! This class of batteries is known as betavoltaics, and they’re powered by the beta-decay of a radioactive material—hence the name. Beta particles are basically just…
