Question

A 40 amp fuse carries a temporary 9 % current overload. How many

amps of current flow through the fuse during the overload?

Answer 1

To calculate the overload current, 9% of the 40 amp original current rating is found, resulting in 3.6 amps, which is then added to the original rating to get a total of 43.6 amps flowing through the fuse during the overload.

The student's question asks for the amount of current that flows through a 40 amp fuse when it carries a temporary 9% current overload. To calculate this, we need to find 9% of the original 40 amps and then add this value to the original current rating of the fuse.

First, we calculate 9% of 40 amps:

0.09 (9%) × 40 amps = 3.6 amps

Now, we add the overload current to the original current rating:

40 amps (original rating) + 3.6 amps (overload) = 43.6 amps

Therefore, 43.6 amps of current flow through the fuse during the overload.

Answer 2

43.6 amp

Explanation:

Given

A 40 amp fuse carries a temporary 9 % current overload.

9% current overload means that whatever will be the normal current carrying capacity of fuse, during overload it carries 9% more than that.

Current carrying capacity of fuse is 40 amp.

during overload it carries 9% more

over load current = 9% of 40 amp = 9/100 *40 = 3.6 amp

total current flowing through fuse during overload = 40 amp + 3.6 amp

= 43.6 amp (answer)
