Next stop on our tour of engineering’s major fields: electrical engineering. In this episode we’ll explore the history of telecommunications, electric power and lighting, and computers. We’ll introduce topics like magnetism, electrical...

Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

Plastics usually stop electricity in its tracks, but scientists have figured out a way to keep the electrons flowing. Hosted by: Hank Green

In this video, we discuss the components of and functions of the electrical conduction system of the heart.

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!

Plastics usually stop electricity in its tracks, but scientists have figured out a way to keep the electrons flowing.

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 video Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object the net total of charge will not change. Grounding allows...

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

Pure water doesn’t conduct electricity; by itself, it is a poor conductor of electricity. However, water contains charged ions and impurities that make it a very good conductor of electricity. We are always told and taught that water...

Band Theory Dissection: Conduction in Various Substances

The band theory of solids is a fundamental concept in solid-state physics that explains the conduction of electricity in substances based on the arrangement of energy levels...

In today's lesson, we delve into the fascinating world of electric motors. Visualize a rectangular conducting loop in a uniform magnetic field – the key to motor magic. As we explore the loop's rotation, we decipher induced magnetic...

The video discusses how devices we use every day are connected to the mains electricity supply. It explains the three types of wires present in a plug - the earth wire, the neutral wire and the live wire - and what each of their...

Electric eels can generate amazing amounts of electricity inside their body. Discover how they use this for defence and to stun potential prey. Physics - Electricity And Circuits - Learning Points. Electric eels create electricity to...

A flash of lightning, and a rumble of thunder. But what exactly are these spectacular occurrences? In 1752, Benjamin Franklin discovered that lightning was caused by powerful electrical discharges in clouds. He wasn’t the first person to...

TOYOHASHI UNIVERSITY OF TECHNOLOGY has developed rubber wheels that conduct electricity by using high frequency electric current. The concept is similar to that of the electric transmission of a train. The road acts like the overhead...

Dr. Forrester defines static electricity by conducting a simple experiment using a balloon. She also identifies the two types of electricity by describing static electricity and current electricity.

Charging by Conduction and Induction are both demonstrated. Each individual step is clearly described. Electrical Ground is introduced and defined. Both demonstrations are illustrated.

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...

Static Electricity demonstrates that an electrically-charged object can attract an uncharged object by conducting an experiment with a charged balloon and paper.

This nugget explains Electrical properties of solids.

Electricity makes our lives easier every day. We use electricity in our work and play. Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. By watching the video and...

In this video we learn how three phase electricity works from the basics. We explain how three phase electricity is generated, how the voltages vary, how to calculate the voltages and vrms, what frequency, hertz and cycle mean and how...
