A fuse wire is a wire of Low resistance and high melting point.

Why the fuse wire should have high resistance and low melting point?

A non-metal having high melting point…………. .

why sodium chloride has high melting point?

The transition elements have high melting points.

Phosphoric acid has high viscosity and high melting point. Why ?

A wire has a resistance of 16 ohm it is melted and drawn into a wire of half its length calculate the resistance of new wire what is the percentage change in its resistance

A wire has a resistance of 32Omega It is melted and drawn into a wire of half of its original length. Calculate the resistance of the new wire. What si the percentage change in resistance?

In comparing the resistance of two cells P and Q with a sides wire bridge, a balance point is obtained when the sliding contact is 30 cm from the zero end of the wire. The resistances P and Q are interchanged and the balance is obtained at 120 cm from the same emf. Find the ratio of the resistance P and Q and the length of the bridge wire
