The correct relation between temperature and resistance of a conductor is given by $R_t = R_{\text{ref}} [1 + \alpha t]$, where $R_t$ is the resistance at temperature $t$, $R_{\text{ref}}$ is the reference resistance (usually at 20°C or 0°C), and $\alpha$ is the temperature coefficient of resistance. This formula shows that the resistance of a conductor changes linearly with temperature, and the symbol $\alpha$ (alpha) represents the rate of that change.
