A resistance thermometer (RTD) is used to measure the temperature of fluid in a container. The RTD resistance changes with temperature according to the following equation: R₁ = R₁(1 + aT), where a = 0.03(°C)-¹, R₁, is the RTD's nominal resistance that equals 30002, and T is the temperature in °C. The RTD forms one arm of a bridge circuit as shown in the figure. The components of the circuit have the following values: R₁-3002; R₂-35002; R3-350052. The resistance of the measuring voltmeter is neglected. Answer the following: A. If the bridge excitation voltage (V) is 15V, calculate the bridge sensitivity in units of volts/ohm. B. Calculate the temperature measurement sensitivity in volts/ °C R %₂ Vi

List the five capacitor replacement rules.
You find that a 25-F capacitor connected to 480 VAC is defective. The storeroom has no capacitors with a 480-VAC rating. However, you find two capacitors rated at 50 F and 370 VAC. Can these two capacitors be connected in such a manner that they can replace the defective capacitor? If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.
