The coating of a zinc layer on iron is called galvanization. This process involves applying a protective zinc coating to iron or steel to prevent rusting and corrosion. Galvanization is widely used in various industries to extend the lifespan of ...
The principle of a fuse is based on the thermal effect of electricity. A fuse wire melts due to the heat generated by an excessive current, thereby breaking the circuit and preventing damage. This thermal effect ensures that the fuse ...
Fuse wire is made of an alloy of tin and lead. This combination is selected because the alloy has a low melting point, allowing the fuse to melt and break the circuit quickly when excessive current flows, thus protecting electrical ...
For normal applications, an electric fuse wire must have a low melting point alloy and be thin with less length. These properties ensure that the fuse wire melts quickly when excessive current flows, breaking the circuit effectively and protecting electrical ...
