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

I need a step by step answer please :)

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 = Ru(1 + aT), where a = 0.03 (°C)-¹, R₁, is the RTD's nominal resistance that equals 30092, 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; R3-350092. 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 V₂
