[" The resistance of wire at temperature "t^(@)C" and "],[0^(@)C" are related by:- "]

The resistances of a wire at temperatures t^(@)C and 0^(@)C are releated by

The resistance R_(o) and R_(t) of a metallic wire at temperature 0^(@)C and t^(@)C are related as ( alpha is the temperature co-efficient of resistance).

The resistance of a wire at room temperature 30^(@)C is found to be 10 Omega . Now to increase the resistance by 10% , the temperature of the wire must be [ The temperature coefficient of resistance of the material of the wire is 0.002 per .^(@)C ]

Resistance of a wire at temperature t^(@)C is R=R_(0)(1+at+bt^(2)) Here, R_(0) is the temperature at 0^(@)C . Find the temperature coefficient of resistance at temperature t is

The resistance of a wire is 5Omega at 50^(0)C and 6Omega at 100^(0)C . The resistance of the wire at 0^(0)C will be
