A thermistor may be assumed to have a linear temperature resistancė dver a range. The variation in resistance is – 0.05°C rise of temperature. The thermistor has a resistance of 1000 2 at 20°C. Calculate the value of its resistance at 25°C. Supposing this thermistor is used in series with a copper coil, what is the value of the resistance of copper coil if the resistance at 20° C and 25°C is the same for the series connected circuit comprising of coil and the thermistor? The resistance temperature co- efficient of copper may be assumed as 0.004 °C.
