- At 25°C, the resistance of a segment of gold wire is 59 . When the wire is placed in a liquid bath, the resistance increases to 193 N. The temperature coefficient is 0.0034 (°C) -¹ -1 at 20°C. What is the temperature of the bath? Answer in units of °C.Suppose you're using a copper wire that has a radius of 0.5 mm, is 3.8 m long, and has a resistivity p=1.7 x 10 8 N- m. What is the resistance of the wire in Ohms?A thermistor is a device whose resistance varies with temperature. At 20∘C∘C a thermistor's resistance is 10.0 kΩkΩ. When connected to a 1.2 VV battery, the current through the thermistor increases by 80 μAμA as the temperature increases to 30∘C. What is the thermistor's resistance at this higher temperature?
