What is the use of fuses?
A.Eliminate shock hazards
B.Prevent fires
C.Save on the cost of electricity
D.Store charge
Answer- Option (b)
Electric fuse uses metal wire which melt when huge current flow through it. In this way it break the continuity of circuit and prevent the fire in appliance.
I will be glad to see your comment if you have any query and thumb up if you are satisfied. Thanks....

In a lot of 200 electrical fuses, 20 are known to be nonconforming. A sample of 10 fuses is selected.(a) What is the probability distribution of the number of nonconforming fuses in the sample? What are its mean and standard deviation?(b) Using the binomial distribution as an approximation to the hypergeometric, find the probability of getting 2 nonconforming fuses. What is the probability of getting at most 2 nonconforming fuses?
Many older homes have electrical systems that use fuses rather than circuit breakers. A manufacturer of 30-amp fuses wants to make sure that the mean amperage at which its fuses burn out is in fact 30. If the mean amperage is lower than 30, customers will complain because the fuses require replacement too often. If the mean amperage is higher than 30, the manufacturer might be liable for damage to an electrical system as a result of fuse malfunction. To...
The mean cost to repair the smoke and fire damage that results from home fires of all causes is $11,389 (HomeAdvisor website, December 2014). How does the damage that results from home fires caused by careless use of tobacco compare? The DATAfile named TobaccoFires provides the cost to repair smoke and fire damage associated with a sample of 55 fires caused by careless use of tobacco products. Using past years' data, the population standard deviation can be assumed known with...

Many older homes have electrical systems that use fuses rather than circuit breakers. A manufacturer of 40-amp fuses wants to make sure that the mean amperage at which its fuses burn eut is in fact 40. If the mean amperage is lower than 40, customers will complain because the fuses require replacement too often. If the mean amperage is higher than 40, the manufacturer might be lable for damage to an electrical system due to fuse malfunction. To verity the...
