WebFeb 16, 2024 · An electrical wire is a conductor, a material which conducts electricity. For household wiring, the material is either copper or aluminium (or copper-sheathed aluminium), although aluminum is not really used anymore. It can be stranded wire or solid metal conductor and in most cases, it is insulated, using a non conductive plastic coating. WebBasically, the fatter the metal conductor inside the wire jacket, the more current it can conduct without generating a lot of friction and heat. To understand this better, imagine electrical wire as if it were a hose carrying water. The more volume inside the hose for the water to flow throught, the less pressure there is on the hose to deliver it. ni health budgetWebApr 11, 2024 · An internationally renowned conductor has revealed how King Charles asked him to perform at King Charles' Coronation..
