Answer: the correct option is FUSE.
Step-by-step explanation:
Current Electricity consists of fast moving negatively charged electrons which travels in materials that allows the flow of electrons called conductors. In the generation of Electricity for distribution, two types of currents are being generated. It's either an Alternating current ( A.C) or a Direct Current ( D.C.). An A.C. consists of electric charges that constantly changes its position and direction of flow of voltage and current while D.C. the electric charge flow in one direction. For the safety of devices of the end users of the electric current ( either A.C. or D.C) generated, a FUSE is usually used to protect the appliances from too much flow of electric current.
A fuse is therefore defined as a safety device that protects appliances( such as televisions, refrigerators, computers) from current overload or voltage fluctuations which can cause damaging effects. It is made up of thin strip or strand of metallic wire with noncombustible material. These devices are usually connected in series with the components to be protected from current overload. This is so because, when there is high or excessive current, the fuse melts and it opens the circuit and disconnects it from the power supply. Some of the types of fuse includes A.C fuse and D.C. fuse.
