उत्तर
- No. The electrician cannot be allowed to replace the fuse in the house with a piece of wire. This is because every wire cannot be used as a fuse filament.
- A fuse filament must have a low melting point such that it could melt and break in response to a large amount of current. Most of the wires have high melting points.
- So, we should always use ISI-marked fuses in our houses to prevent short circuits.
