Save guides, add subjects and pick up where you left off with your BBC account. Narrator: Problems with your fan Frank? Fixing this will be a breeze! Huh-huh. This is e-e-a-sy, for electricity to ...

These patterns control the flow of current using electrical switches ... are built by adding thin layers of conductive metals, insulators and more silicon to the entire wafer, sketching out ...

Contact: j.murdock@newsweek.com Scientists in Canada have shown off a groundbreaking way of controlling electrical currents ... as being conductors or insulators, depending on their ability ...

Alumina is the most commonly used type of ceramic and is available in purities up to 99.9%. Typical applications inlcude electrical insulators; seal faces; valve seats. For many years fish spine beads ...

Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...

They may seem like just the finishing touches, but splices and terminations are critical components of any electrical system. The Code requires you to follow ...

2D topological insulators, also known as 2D quantum spin Hall insulators, are materials that are electrical insulators in the bulk but can conduct electricity extremely well on their edge via special, ...

Topological insulators are a hot topic in condensed-matter physics on account of their special properties. Electrical insulators in the bulk, these materials have surface states that conduct electrons ...

And you can touch the wire and the outer casing of the electrical items without worrying about getting a shock. Other insulators, which don’t allow electric current to flow through them ...
