A fuse is used to protect electric circuits from too much electricity running through them. How should a fuse be hooked up with the components it is designed to protect? Justify your answer.

Responses
A A fuse should be hooked up in series because all the current must flow through the fuse in a series circuit.
B A fuse should be hooked up in parallel because all the voltage must flow through the fuse in a series circuit.
C A fuse should be hooked up in parallel because all the current must flow through the fuse in a parallel circuit.
D A fuse should be hooked up in parallel because all the voltage must flow through the fuse in a parallel circuit.

Answer 1

A. A fuse should be hooked up in series because in a series circuit, the current must flow through each component in the circuit, including the fuse. Placing the fuse in series ensures that all the current passing through the circuit also passes through the fuse, allowing it to protect the components from excessive current flow. If the fuse were hooked up in parallel, it would not properly protect the components as not all of the current would flow through it.
