Hello Aspirant,
An electrical fuse is a current interrupting device which protects an electrical circuit in which it is installed by creating an open circuit condition in response to excessive current.
When the element in a fuse receives too much heat it will melt and interrupt the current. Fuses are usually used as a conduit between an electrical power source and an electrical component or a combination of components arranged in an electrical circuit. A fusible link is connected between the fuse terminals. This means that when an electrical current passing through the fuse goes beyond what the device is able to handle, the fusible link will melt and the circuit opens thus preventing electrical component damage.
Hope this helps you
All the best for your future
