Q. Why is tungsten not used in a fuse wire?

Answer. In a fuse wire such a metal should be sued where resistance is high but melting point is low, so that when accidentally high current passes through the circuit the fuse wire is very much heated due to its high resistance and easily melts due to its low melting point and thereby breaks the circuit. As the melting point of the tungsten is very high, it is not suitable to be used as a fuse wire?
