Temperature co-efficent of resistance for metals is

The temperature coefficient of resistance of an alloy used for making resistor is

The temperature coefficient of resistance of an alloy used for making resistor is

Resistance or coil at 100^(@) C is 4.2 Omega . If temperature co-efficient of resistance of material is 0.004 (""^(@)C)^(-1) so what will be its resistance at 0^(@)C ?

The temperature co-efficient of resistance of a wire at 0^(@)C is 0.00125^(@)C^(-1) . At 25^(@)C its resistance is one ohm. The resistance of the wire will ne 1.2 ohm at .
