Earthing (or grounding) is a vital safety measure in electrical systems. It ensures that any leakage of current from faulty wiring, insulation failure, or damaged appliances is safely directed into…
Household electrical appliances are always connected in parallel rather than in series because of both safety and functionality. In a parallel connection, each appliance receives the same voltage as the…
Tungsten is used as the filament material in electric bulbs because it has several properties that make it ideal for producing light through incandescence. When an electric current passes through…
An electric bell works on the principle of electromagnetism and includes a coil, iron armature, spring, and hammer. When the switch is pressed, electric current flows through the coil, turning…
Electric fans run at different speeds with the help of a device called a fan regulator, which controls the amount of voltage or current supplied to the fan’s motor. The…
Capacitors are among the most useful components in electronics. One of their fascinating behaviors is that they block direct current (DC) but allow alternating current (AC) to pass through. Let’s…
A short circuit happens when the current in an electrical circuit takes an unintended shortcut through a very low-resistance path. This sudden change causes sparks, excessive heating, and sometimes even…
A fuse is one of the simplest yet most important safety devices in an electrical circuit. Its main function is to protect appliances and wiring from damage caused by excess…
When it comes to transmitting electricity over long distances, the choice of conductor material is crucial. While both copper and iron can conduct electricity, copper is overwhelmingly preferred for electrical…
Have you ever noticed that when you switch off an electric fan, it doesn’t stop immediately? Instead, it keeps rotating for a while and gradually slows down until it finally…
