A thermometer can be made from a brass wire (temperature coefficient of resistivity 0.00150°C^-1 at 20.0°C) which has a potential difference of 1.50 V between its ends and is connected to an ammeter. A measurement determines that the current flowing through the wire is 347 mA when the wire is at room temperature (20.0°C). (a) What is the resistance of the wire? (b) What change in current will accompany a decrease in temperature of one degree Celsius (or one kelvin)? Be careful of the sign of your answer. (c) How much current flows through the wire when the temperature is 35.0°C?
