Question

For a good fuse the value of the fusing factor is:
1. always zero
2. always more than 1
3. always less than 1
4. always equal to 1

Answer 1

Correct Answer - Option 2 : always more than 1

Fusing factor:

• The fusing factor is the ratio of minimum fusing current and the current rating of the fuse.
• Minimum fusing current is the minimum value of current due to which fuse melts.
• The current rating of the fuse is the maximum value of current due to which fuse does not get melted.
• The fusing factor of a fuse is always more than 1
