Fuse are series path load for protecting device from short
circuit. or overload protection from high value current also
voltage drop Resistance may change when a fuse becomes hot
due to energy dissipation while conducting higher currents.
The speed at which a fuse blows depends on how much current
flows through it and the material of which the fuse is made.

The operating time is not a fixed interval, but decreases as
the current increases. Fuses have different characteristics
of operating time compared to current, characterized as
fast-blow, slow-blow, or time-delay, according to time
required to respond to an over current condition. A standard
fuse may require twice its rated current to open in one
second, a fast-blow fuse may require twice its rated current
to blow in 0.1 seconds, and a slow-blow fuse may require
twice its rated current for tens of seconds to blow.
