Solution
The correct option is A fuse
The explanation for the correct option (A):
- Fuse is a device that protect circuit from excessive current.
- It is commonly consists of a current conducting wire of easily fusible metal that melts, and thus interrupts the circuit whenever there is excessive current flow in circuit.
The explanation for incorrect options (B), (C), and (D):
- Switch is a device used for making and breaking electric current through the circuit.
- An inductor is a simple component that store energy in the form of magnetic energy.
- Conductors are the substance which allow electricity to pass through them.
Therefore, option A is the correct choice.
