Question

1. The fuse current in amperes is related to
fuse wire's diameter is :​

Answer 1

Answer:

The fuse current is directly proportional to the fuse wires diameter.

Explanation:

This can be explained as the resistance is inversely proportional to the area of cross section of wire i.e. πr^2.

So we can say that greater the radius, greater will be the area of cross section and hence lesser will be the resistance.

We know that lesser will be the resistance (property to oppose charge), greater will be the current.

Hence, Greater will be the diameter of fuse wire, greater will be the current and vice-versa.
