Question

In an electric circuit, explain why a fuse is always connected in series.

Answer 1

1. Fuse is a safety electrical device that protects appliances from high currents.
2. When a fuse is connected in series, the fuse wire fuses out and the circuit becomes an open circuit and will stop the flow of current.
3. When a fuse is connected in parallel and the fuse wire fuses out the circuit would be not affected and the current will flow in other branches.
4. Hence, in an electric circuit, a fuse is always connected in series because when the fuse wire fuses out the circuit becomes an open circuit, and this stops the flow of current in a circuit
