Regarding the Resistor, this article will explain the information below. Resistance Temperature CharacteristicsTemperature Coefficient of Resistance Resistance Temperature Characteristics In general, the resistance of metals increases with increasing temperature, while the resistance of semiconductors decreases with increasing temperature. This change in resistance with temperature can be calculated using the temperature coefficient of resistance \(α_t\), which can be expressed by the following equation: \begin{eqnarray}R_T&=&R_t+α_tR_t(T-t)\\\\&=&R_t\left\{1+α_t(T-t)\right\}\tag{1}\end{eqnarray} , where \(R_T\), \(R_t\), and \(α_t\) indicate the following: \(R_T\):Resistance at temperature \(T{\mathrm{[℃]}}\), units of \({\mathrm{[Ω]}}\).\(R_t\):Resistance at temperature \(t{\mathrm{[℃]}}\), units of \({\mathrm{[Ω]}}\).\(α_t\):Temperature coefficient of resistance. In equation (1), the resistance \(R_t{\mathrm{[Ω]}}\) is obtained when the temperature changes ...
