Why does resistance of a metallic conductor increase with increase in temperature?
Is there any practical application of the increase in resistance of metals with temperature?
Yes! One common application is in electric fuses. Fuses are designed with a wire that has a specific resistance, and when the current passing through the fuse exceeds a certain limit, the wire heats up and melts to break the circuit. This protects devices from overcurrent and prevents damage, such as in electrical circuits at home.
