Why Does Graphite Conduct Electricity? Graphite is one of those fascinating materials that seems to defy expectations. Unlike most non-metals, it conducts electricity something we usually associate with metals like copper or silver. But why? Let’s dive into the science behind graphite’s electrical conductivity and explore why this everyday material is so special. The Unique Structure of Graphite What Makes Graphite Different? Graphite is made up of carbon atoms arranged in layers. Each layer consists of hexagonal rings, much like a honeycomb. These layers are called graphene sheets, and they’re only weakly bonded to each other, which is why graphite feels slippery (it’s often used in pencils!). But here’s the key: within each graphene sheet, carbon atoms share delocalized electrons. These electrons are free to move, allowing electricity to flow similar to how electrons move in metals. Why Don’t Other Forms of Carbon Conduct Electricity? Not all carbon-based materials conduct elec...

IEC 60364 Electrical Installations for Buildings

IEC 60364 Electrical Installations for Buildings is the International Electro technical Commission's international standard on electrical installations of buildings. This standard is an attempt to harmonize national wiring standards in an IEC standard. The latest versions of many European wiring regulations (e.g., BS 7671 in the UK) follow the section structure of IEC 60364 very closely, but contain additional language to cater for historic national practice and to simplify field use and determination of compliance by electrical tradesmen and inspectors. National codes and site guides are meant to attain the common objectives of IEC 60364, and provide rules in a form that allows for guidance of persons installing and inspecting electrical systems. The standard has several parts: Part 1: Fundamental principles, assessment of general characteristics, definitions Part 4: Protection for safety Section 41: Protection against electric shock Sectio...

When Was Electricity First Used in Homes? The Shocking History

The Dawn of Electric Light: When Was Electricity First Used in Homes? Electricity is something we take for granted today, but there was a time when homes relied on candles, oil lamps, and gaslight. So, when was electricity first used in homes? The answer takes us back to the late 19th century, a time of innovation and bold experiments that forever changed how we live. In this article, we’ll explore the fascinating journey of residential electricity—from its earliest experiments to the moment it became a household necessity. The First Homes to Use Electricity The Early Experiments (1870s-1880s) Before electricity became widespread, inventors like Thomas Edison and Nikola Tesla were hard at work. Edison’s Pearl Street Station in New York City (1882) was the first commercial power plant, supplying electricity to a handful of wealthy homes and businesses. These early adopters enjoyed electric lighting, a luxury that replaced sooty gas lamps and fire hazards. However, most Americans w...
