Question

Mark the correct reason why a fuse is always connected in series
(A) When fuse melts, it breaks down the entire home circuit and no current flows
(B) In series connection, the current for the entire house pass through the fuse
(C) Both
(D) None

Answer 1

Hint: We are asked which one of the following options is right based on an electric fuse. We can start to answer this question by defining what an electric fuse is and how it works. We can also state the purpose of an electric fuse. This will lead us to our required answer.

Complete Step By Step Answer:
Let us start by defining what an electric fuse is. An electric fuse is a device that is installed in order to protect from overcurrent on an electrical circuit. The main component is a metal wire that melts when a current higher than it is supposed to be flowing through it. This melting stops the electricity from flowing. The substance used in an electric fuse should have a lower melting point This allows the wire to melt as soon as the amount of electricity through it passes a certain amount.
Fuse is always connected in series because when fuse melts, it breaks down the entire home circuit and no current flows through it and in series connection, the current for the entire house passes through the fuse.
In conclusion, the right answer is option (C) Both.

Note:
An electric fuse is a very helpful device. Sometimes they help to not overpower other devices. Electric appliances have a power rating which tells us how much electricity it need to work. When electricity becomes too high than the power rating, it might damage the appliance. Thus, we need an electric fuse so that this does not happen.
