Today, we'll explore the materials electrical engineers work with. We'll look at high-conductors, insulators, and how low-conductivity conductors can be used to generate light and heat.

In this episode of Crash Course Physics, Shini talks to us about how power gets to our homes. It's kind of amazing when you think about it and much more complicated than it may seem!

When you imagine the energy of the future, solar power is probably in the picture – but in recent years, less than 2% of the world’s electricity has come from solar power. Here are 5 new inventions that are likely to change that.

Hank builds a simple electric motor just powerful enough to make a small screw spin, but also strong enough to blow your mind.

In this video Paul Andersen explains how energy can be transferred from one system to another. In a closed system the energy can be transferred as either work or heat. Thermal energy transfer is know as energy transfer through heat. ...

Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between...

What Happens To Your Energy when you Die? During the time that you will be watching this video, 500 people around the world will die. Their thoughts, their hopes, their dreams no longer with us. ...

Cryptocurrencies are heralded as the technology of the future. But Bitcoin, and others like it, are putting that same future at risk, with their devastating effect on the environment.

“Interconnected Ecosystems” explores interdependent relationships between living things in various biomes.

The law of conservation of energy tells us that energy is neither created or destroyed - just converted from one form to another. This means that we cannot make energy from nothing and energy does not just disappear. Energy, however, can...

This video explores how energy can be transferred from place to place. Throughhands-on activities students investigate how sound and electrical energy is transferred. This program correlates to the following Next Generation Science...
