This is a lecture video explaining how loudspeakers work by utilizing the motor effect, which is when a current-carrying conductor experiences a force when placed in a magnetic field. The video demonstrates this effect on a conductor...

This nugget explains the concept and construction of a capacitance and its unit of measurement.

People throw around the term "electrolyte" quite a bit, but what does it mean? What makes something a strong electrolyte, a weak electrolyte, or a nonelectrolyte? let's find out!

This video explains the process of electricity generation on an industrial level. It describes how a voltage and current can be induced in a conductor by moving it relative to a magnetic field, and compares two types of electricity...

Solar panels are rectangular objects made up of individual solar cells, which capture sunlight and generate electricity. These cells are made from silicon, a semiconductor material found in sand. When sunlight hits the cells, it causes...

It explains construction of an electric generator and the working of an AC and DC generator and its differentiation.

This nugget explains the mechanism of movement of electric charges in a current-carrying conductor.

This video shows how to use a few simple materials (lightbulb, batteries, and alligator clips) to create a circuit to light up a lightbulb. From there, the video shows how to use the circuit to experiment and determine if various...

This nugget explains the forces of attraction and repulsion between two current carrying conductors. It also explains the working of Roget's spiral to illustrate these phenomena.

Whenever you plug something into an electrical socket, don't you wonder what's going on? Well you should, as it's pretty neat. What is electricity made of? How did we figure out how to harness this power? Let's take a look!

This video describes the basic role that atoms play in creating electrical charges, as well as the nature and creation of static electricity. Various methods of charging are discussed, emphasizing the role that insulators and conductors...

Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!

This live-action video program is about the word Underground Railroad. The program is designed to reinforce and support a student's comprehension and retention of the word Underground Railroad through use of video footage, photographs,...

This video explains the importance of metals in our daily lives and their unique properties. It discusses how metals are made up of atoms held together by metallic bonds, where positively charged ions are surrounded by a sea of...

A common mistake for beginner Spanish learners is to assume that a Spanish word and and an English word that look or sound alike has the same meaning. In this lesson, you'll learn which words are "false cognates". False cognates may look...

Would you like to include LED lights in a painting or greeting card? This video will show you how. Paper circuits are made with just a few simple items; you can use a battery and some copper tape to add tiny lights to your project. The...

Choral Director Simon Halsey discusses how a really great conductor can get the most out of every part of the orchestra.

This video describes the basic role that atoms play in creating electrical charges, as well as the nature and creation of static electricity. Various methods of charging are discussed, emphasizing the role that insulators and conductors...
