Detailed Solution

The given statement is False.
Electric Fuse is a safety device that protects electric circuits and appliances by breaking the flow of any unduly high electric current. It is a low melting point copper or other metal wire that breaks down due to heat caused by high voltage or overload to avoid short circuits or any damage to the device. When the fuse rating is

5 A

, the fuse wire will easily melt, preventing the electric appliances from being damaged.
The melting point will be high if we use a fuse wire of a larger rating (

15 A

). The fuse wire won’t break the current flowing to the circuit, damaging the electric appliances.
Therefore the correct statement would be that we cannot replace the fuse wire from the defined rating with a larger rating.
