The temperature coefficient of resistance of a wire is 0.00125/ ""^(@)C . At 300K its resistance is 1Omega . The temperature at which the resistance becomes 2Omega is

A wire has a resistance of 2.0 Omega at 25^[o)C and 2.5 Omega at 100^(o)C . Find temperature coefficient of resistance of the wire?

A heating element using nichrome connected to a 230V supply draws an initial current of 3.2A which settles after a few seconds to a steady value of 2.8A. What is the steady temperature of the heating element if the room temperature is 27.0^(o)C ? Temperature coefficient of resistance of nichrome averaged over the temperature range involved is 1.70 x 10^(-4) ^(0)C^(-1)
