Fuse wire not used in circuit containing electric cell
Explanation:
- Fuse wire is used to prevent sudden excess flow of current. Cell provide current of fix magnitude so fuse wire are not used in circuit containing electric cell.
- An electric fuse wire is a wire made up of an alloy of low melting point and having a current rating lower than that of the rating of the appliance. It is connected in series with the appliance in the phase (incoming) part. It is a measure of safety and protection for the appliance.
- When the faulty current (large in magnitude) passes through the wire heats up due to joule's effect as a result it melts thus opening the circuit and protection assured.
