A. Zero
B. One
C. More than one
D. Less than one
Select the correct answer from the above-given options and support your answer with a proper explanation after selecting the answer.

Answer: C. More than one

The fusing factor should be equal to more than one.


If the current in the circuit exceeds a permissible level then it may damage the appliances, to prevent this we employ the fuse wire that will melt down and isolate the circuit if the current passes through the circuit is greater than the permissible limit.

Fusing factor=minimum fusing current/ current rating of the fuse

Hence for the proper operation minimum fusing current (permissible limit of the current) must be greater than the current rating of the fuse, then only the fuse can isolate the circuit in case of excessive current flow due to overload or fault.

The fusing factor should be equal to more than one.
