1. 1. an automatic device for stopping the flow of current in an electric circuit as a safety measure. 2. fuse is anelectrical safety device that operates to provide overcurrent protection of an electrical circuit. 3. Thedevice which takes electrical energyis known as the electric load. In other words, the electrical load is a device that consumes electrical energy in the form of the current and transforms it into other forms like heat, light, work, etc. The electrical load may be resistive, inductive, capacitive or some combination between them. 4. a control device such as a switch, fuse/circuit breaker, or relay that may be used to stop, start and or regulate the flow of electricity.
