Consider a fuse for electrical equipment. It is designed to disconnect at 2 A after a delay of 100 ms. The operation of the fuse is based on heating of a thin wire. When the temperature reaches the melting point, the wire fuses. Classify the device in all possible ways.

Solution

Sensor: a device that converts a physical parameter to an electrical output.

Actuator: a device that converts an electrical signal to a physical output.

Here the fuse takes the electrical signal that is current and disconnects after heating of thin wire which is nothing but physical output.

Hence FUSE is an actuator.
