ELECTRICITY TRANSMISSION AND DISTRIBUTION

This DVD resource explores how the UK's electricity distribution and transmission network works. It looks at why transmitting electrical energy over large distances involves energy losses and examines how these can be minimised. It explains why electricity is transmitted at very high voltages from power stations to where its needed, how variable transformers are used to maintain constant voltage as demand increases, and the role of circuit breakers both on the national grid and in your own home.

UNDERSTANDING ELECTROMAGNETISM

From lighting to the Internet, none of this would have been possible without Faraday's work in the field of electromagnetic induction. Made with the help of the Royal Institution this film gives a clear explanation of the principles and concepts behind electricity generation, transformers and motors. It explains electromagnetic Induction and then goes on to look at how Faraday's laboratory models have evolved to become the generators, transformers and motors, that underpin modern society.

ONE FLASH AND YOU'RE ASH! WORKING SAFELY WITH ELECTRICITY

Working with electricity is potentially dangerous. If something does go wrong and someone is injured, knowing how to deal with the situation, and treat the victim, can save lives. This program explores electrical safety. Guided by an engaging presenter and qualified electrician, it examines the dangers of electricity, the cause, effect and treatment of electric shock, and how to avoid the dangers. It explains risk management, testing for dead, electricity and water, the effects of different levels of current on the body and first aid techniques to administer to shock victims, including the DRABCD procedure.

PRINCIPLES OF PHYSICS 2: SOUND, MAGNETISM, ELECTRICITY AND RADIOACTIVITY

Physics is a science that describes how things work. Almost everything around us can be explained in terms of the principles of physics. With the use of practical demonstrations related to common activities, this program investigates some of the key concepts of physics. Using a drum kit we look at how sound works, how we make it, and how it gets around. We investigate electricity and electromagnetism and compare the similarities between a remote control car and a mobile phone charger. Finally, we take a look at radioactivity and discover a radioactive device that can be found in almost every family home.

INQUISITIVE MINDS

Join Dr. Knowledge as he takes young viewers on a fast-paced adventure and learn about energy and electricity. Students will observe real-time demonstrations and scientific exploration in a fun and entertaining way.

Inquisitive Minds: Energy and Electricity will show what tools, appliances, factories and everything from iPods to airplanes have in common. Each needs energy to do their jobs. But, where does that energy come from? We know we can get our power from a wall outlet, but that's only the beginning. Dr. "K" and the IM team will trace the electricity from the wall through the "power grid" to its source. Students will learn how power is generated, what makes it travel through wires and learn about the path it takes to get it to where it's needed. How does it work? There's a lot to learn about Energy, come along!

Inquisitive Minds was created to help students develop a better understanding of the connections between the environment and energy and providing thought-provoking discussions that just might lead to energy conservation solutions of their own!

INTRODUCTION TO ELECTRICITY

This program introduces the concept of electricity to the student who has used this source of energy all his or her life but has never really understood where it comes from and how it works. It gives a little of the early history and covers static and current electricity, how to measure it and sources of it. Clear graphics and illustrative footage explain the concept of current, resistance and voltage. Students are shown where our electricity comes from and a large range of examples of where it is used. It is also stressed that this precious resource should not be wasted and why. A comprehensive and engaging introduction to this vital topic.

DC ELECTRICITY: DISCOVERY AND DEVELOPMENTS

This program looks at the origins of electricity through the first uses of static electricity by the Greeks, Gilbert and onto other popular displays by scientists in the 18th and 19th centuries. Viewers will gain an understanding of the chemical battery, the 'complete' circuit, electrolysis, electroplating and negatively charged electrons. Resistance to flow is introduced and the use of both ammeters and voltmeters to monitor flow and potential. Highly effective animations will engage students, while clearly demonstrating processes.

SERGEANT MAGNET OF THE ELECTRON ARMY: HOW ELECTRICITY WORKS AT THE ATOMIC LEVEL

Another video in our Animated Series. The light switch goes on and Sergeant Magnet sets off to recruit loosely held electrons to answer the call. He trains them to move forward as the magnet moves sideways across the wire. Then he sends them on a long range mission where the wire narrows and they meet resistance. They bounce along through the filament losing energy and exciting the atoms to give off light. They wonder if resistance is useless after all.

ELETRICITY: FORCE THAT CHANGED THE WORLD

The Force that Changed The World documents the massive change electricity has had on the civilized world over the past century, and what it holds for the future. The ancient Greeks first discovered attractive electric forces when they rubbed amber with wool. In 1600, William Gilbert discovered that glass and diamonds behaved like amber and called these materials electrics, based on the term electrum, the Latin word for amber. From Ben Franklin to Alessandro Volta, Andre Ampere, and George Ohm, advances in understanding electricity were made. From the telephone to the television and from the refrigerator to air conditioning, we have reached the point where the whole world is but a key stroke away.
