Electric fuse is a protective device which protects electrical equipment in the circuit by breaking the circuit when there is a short circuit.It contains a fuse wire which has low resistance, it allows normal current tpass through it safely but if there is any short circuit, fuse will blow out i.e fuse wire cant withstand the heat produced by that ...
Used in antique spring-powered mechanical watches and clocks, a fusee is a cone-shaped pulley with a helical groove around it, wound with a cord or chain which is attached to the mainspring barrel.ost fusee clocks include a 'winding stop' mechanism to prevent the mainspring and fusee from being wound up too far, possibly breaking the chain. As it is wound, the fusee chain rises toward the top of the fusee.
