Question

suggest an experimental setup to illustrate the action of an electric fuse​

Answer 1

Answer:

Aim :- illustrate the action of an electric fuse. 

apparatus :- a thin strip of  aluminium foil of length 5cm, two iron nails, require length of electric wire,battery , plug-key and a bulb.

Experiment :- decorate the all apparatus like as pic.

 now switch on the circuit, you see that the aluminium strip burns out immediately and the circuit break and stop the flowing of current.

   this is how a electric fuse works the using of heating current and protect the household appliances for getting damaged, unusual high current due to short circuit ,power fluctuation in the electric line etc.

Answer 2

Answer:

Take a paper cup and fix two metal drawing pins inside of the cup at the bottom of the paper cup by leaving a small gap between them. Now make an electric (open) circuit by connecting these pins to thin conducting electric wires, a switch and a D.C. cell in series.

Now take another cup which can be fixed in the above mentioned cup, fix two metal drawing pins outside of the cup at the bottom of the paper cup by leaving a small gap between them such that these pins touches the pins of the first cup if this cup is fixed in to the first cup now connect the these two pins with a fuse wire.

Your electric fuse is ready.
