Electric Circuits Part 5 – Effects of the Electric Current , the Fuse


Hi and welcome to part 5 of the introduction to Electric Circuits! In this part: Main effects of the electric current. The three main effects of an electric current are: magnetic, chemical and heating effect. Some of the most common practical applications of the effects of an electric current include: relays, bells, motors, generators and transformers for the magnetic effect. Electroplating for the chemical effect. And cookers, water heaters, electric fires, irons for the heating effect. A fuse is used to prevent overloading of electrical circuits. The fuse, which is made of material having a low melting point, utilises the heating effect of an electric current The fuse is placed in an electrical circuit and if the current becomes too large, the wire melts and so breaks the circuit. And now a practical example: This concludes the 5th part of the introduction to electrical circuits. Share this if you found it useful! Thank you and goodbye!
