  1. A platinum resistance thermometer (PRT) is part of a voltage divider circuit to measure temperature. The reference voltage is 3.30 V and the fixed reference resistor (RREF) is 1000 W. The PRT is designed to have a resistance of 1000 W at 20 oC. If the measured output voltage across the PRT is 1.66760 V, determine the temperature measured by the PRT. (Retain 5 decimal places in your calculations.)

Part 1: I need to design a circuit using only resistors and capacitors that will filter out a signal above a specific frequency. In order to be deemed a success, the peak voltage across your capacitor must be equal to 20% of the peak voltage provided by the function generator at the frequency f_theory. Full credit on this lab requires that your percent error in Part 2 is less than 5%. f theory = 1699Hz Available values of resistance are...

A 5-kW, 220-V shunt motor has an armature resistance of 0.15 ? and a field-circuit resistance of 100 ?. The motor delivers rated output power at rated voltage when its armature current is 20 A. When the motor is operating at rated voltage, the speed is observed to be 1000 r/min when the machine is loaded such that the armature current is 15 A. In order to protect both the motor and the dc supply under starting conditions, an external...

2. You are using a digital multimeter (DMM) to measure the voltage across a resistor. The values displayed on the DMM vary, with five consecutive values being 2.412, 2.432, 2.418, 2.422, and 2.416 V (this happens even though no connections are changing). These fluctuations give rise to an uncertainty in the measured value of resistance. a) (1 point) One method of quantifying the uncertainty in the measurement is to take half of the range of the largest fluctuating digit.
