like “Shock Risk”. Always be observant of such signs and follow the safety rules established by the electrical code followed by the country you’re in. 5. Always put a cap on the hot/live wire while working on an electric board or service panel as you could end up short circuiting the bare ends of the live wire with the neutral. The cap insulates the copper ends of the cable thus preventing any kind of shock even if touched mistakenly. SAFETY BY EARTHING:- In electricity supply systems‚ an earthing

The Science of the Spud — a History of the Potato Battery Experiment There are hot potatoes‚ french fried potatoes‚ baked potatoes and scalloped potatoes. There are potato chips‚ potato pies and potato soufflés. Last‚ but not least‚ there’s the potato battery. Who on earth invented the electric spud? Why does it work? For that matter‚ why would anyone want to see if a potato could conduct electricity in the first place? Well‚ we may never be able to answer some of the questions this quirky experiment

cylinder. | | A wire is a single‚ usually cylindrical‚ flexible strand or rod of metal. Wires are used to bear mechanical loads and to carry electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Standard sizes are determined by various wire gauges. The term wire is also used more loosely to refer to a bundle of such strands‚ as in ’multi-stranded wire’‚ which is more correctly termed a wire rope in mechanics‚ or a cable in

that it might be possible to send a coded message over a wire. While a student at Yale College a few years before he invented the electromagnet‚ had written his parents a letter about how interesting he found the lectures on electricity. Without what he learned at Yale‚ Morse found when he began to develop his idea that he had little real understanding of the nature of electricity‚ and after many attempts to work with batteries‚ magnets‚ and wires‚ he finally went for help to a college
