At what temperature (in \deg C) are their resistances equal?A platinum resistance thermometer has a resistance R0 = 50 Ω at atemperature To of 20 °C. The temperature coefficient of resistance for theconductor for Pt (α) is 3.92 x 10-3 (°C)-1. The thermometer is immersed in avessel containing molten tin, at which point the resistance increases to 92.8Ω. What is temperature of the liquid tin?(a) Of what material is a wire made, if it is 20.0 m long with a 0.110 mm diameter and has a resistance of 33.5 at 20.0°C? copper gold platinum silver (b) What is its resistance (in Q) at 140°C? 47.17
- A silver wire has a resistance of 2.00 Ω at 34.0°C. Determine its resistance (in Ω) at 434°C. The temperature coefficient of resistivity for silver wire is 3.80 ✕ 10−3 (°C)−1. (Assume that the temperature coefficient of resistivity was measured using the reference temperature 20°C.)Gold is the most ductile of all metals. For example, 2 gram of gold can be drawn into a wire 2.4 km long. The density of gold is 19.3 x 103 kg/m3, and its resistivity is 2.44 x 10-8 Vm. What is the resistance of such a wire at 20.0°C? 2984 Ohms 1356 Ohms 1356250 Ohms 565OhmsPlatinum is commonly used as a resistance thermometer since Platinum is relatively free from corrosive effects and has a high melting point. Suppose that at 20 oC the resistance of a Platinum wire is 164.2 Ω. When this wire is placed in a solution, the resistance of the wire becomes 187.4 Ω. What is the temperature of the solution? The temperature coefficient of resistivity of Platinum is α = 0.00393.
