Electric fuse and its working

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. You should know how the fuses or circuit breakers, which are used to protect electrical circuits and appliances, work. This protects the wiring and the appliance if something goes wrong.

A secondary school revision resource for AQA GCSE Additional Science about electricity and mains electricity. A spring-loaded push switch is held in the closed.

Use this simulation to see how circuit breakers work.

The verb fuse means to melt.

A fuse is an overcurrent responsive safety device used to protect an electrical circuit from the effects of excessive current. It is placed in series with the electrical circuit it is intended to protect. If lightning strikes near your home, all that electricity .

I start with the screw in fuse used in many older homes, how it works what its limitations are. This video is part of the heating and cooling series of train. Another type of fuse holder for cartridge-type fuses is commonly used for installation in equipment control panels, where it is desirable to conceal all electrical contact. It connects the live pin of the plug to the live wire. This breaks the circuit and disconnects the appliance.

The working of the fuse depends on the heating effect of the current. In normal operating condition, the normal current passes through the fuse. The heat develops in the fuse . Its operation is completely automatic and requires less time as compared to circuit breakers.

Blowing on the wire is sufficient to reduce its resistance and increase the current very considerably. Holding the wire between the fingers has the . It provides fused over-current protection through the use of different fuse types . Without circuit breakers (or the alternative, fuses ), household electricity would be impractical because of the potential for fires and other mayhem resulting from simple .
