Damaged leads or defective electrical equipment can lead to
short-circuits. The actual piece of electrical equipment - or more
accurately, its resistance - are hereby circumvented. The result is
an inadmissibly high current, which can cause a fire to break out
because of the resulting excessive heating up of current-carrying
parts.
In this experiment, students should learn the principle on which
the simplest and oldest safety device, the safety fuse,
functions.
How can electrical appliances be protected from catching fire
when a short-circuit occurs?
Set up a circuit containing a model of a safety fuse and use it
to examine the function of an electric fuse.
