The temperature coefficient of resistance (TCR) is a measure of how the resistance changes with temperature. It is expressed in ppm/°C or ppm/°K and calculated as: TCR = (R2-R1)/(R1(T2-T1)) x 10^6 The variation of resistance with temperature is given by: R(T2) = R(T1) [1 + αΔT], where α is the temperature coefficient of resistance and ΔT is the temperature difference. Alternatively, the variation of resistance with temperature can be expressed as: ρ = ρ0e^(α(T-T0)), where ρ is the resistivity and ρ0 is the resistivity at a reference temperature T0. The absolute thermal resistance is the ratio of the temperature difference across a material to the heat flux through it. It is expressed in K/W or °C/W and calculated as: Rth = ΔT/Q, where Q is the heat flux.
