What is an electric fuse? How is it connected in a circuit?
Fuses are always connected in series with the component(s) to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component(s).
An electrical fuse is a safety device that operates to provide protection against the overflow of current in an electrical circuit. Fuses are always connected in series with the component to be protected from overcurrent, so that when the fuse blows (opens) it will open the entire circuit and stop current through the component.
