    Electrolysis is used to coat objects with a layer of other materials... Such as chromium is a good material to make things out of, but it's expensive, so people use electrolysis to coat a layer of chromium on a cheaper material. Other uses are: car bumper, wheel rims etc.

    The largest organ in the human body is the one you can see most easily: the skin. The skin is considered an organ because it has some very specific functions — like maintaining body temperature and protecting the other organs from bacteria — that require some specialized tissues.

    The skin of an average adult has a surface area of over 21 square feet and accounts for 6% to 10% of your body weight, edging out the liver, your body's second-largest organ, which accounts for approximately 2.5% of your body weight.

    The fuse is a reliable overcurrent protective device, primarily used as a circuit protection device for overcurrents, overloads and short-circuits.
    The heating effect of an electric current can be dangerous. If a circuit overheats it could cause a fire. To avoid overheating, circuits often contain a fuse. Fuses contain a low resistance wire made of a metal with a low melting point.
    Different circuits need different strength currents and so we need different types of fuses. Some fuses can only handle a little bit of heat, some can handle a lot. We choose the fuse that suits the safety needs of our circuit. If the circuit overheats, the fuse will melt and break the circuit to reduce the danger of fire as well as protect electronic equipment.
