Design an amplifier to sense open-circuit output voltage from a transducer and provide proportional current through a load resistor. The series resistance of the transducer is a range between 1 kOhms and 10 kOhms. The load resistance is a range between 1 kOhms and 10 kOhms. The change in load current in response to change in these resistance values is not more than 10%. For a nominal transducer output voltage of 10mV, the current through the load resistor is at least 1mA.
The air conditioner in a house or a car has a cooler that brings atmospheric air from 30 degree c to 10 degree c both states at 101 kPa. if the flow rate is 0.5 kg/s find the rate of heat transfer.
Problem on complex power, An electric load operates at 240 volts. The load absorbs an average power of 8Kw at a lagging power factor of 0.8.
A window is etched through a 500 nm thick oxide on a [100] silicon wafer. The wafer is re-oxidized at 1100 °C using wet oxidation to grow a 750 nm thick film inside the window. Draw a cross-section of the wafer following the second oxidation.
Design a timer system that has a push button, LCD and RTI. When you press the push button, the timer starts counting each second and displays the seconds' value on the LCD. When you press the timer, the system stops counting.
a) Based on your decision create a sampled signal of the sum of the two sines, and plot the magnitude of the zero centered FFT with property frequency annotation. Did it work Check with the data tip tool.
A purely inductive load of 10 ohms is connected to an ac source of 120 V (rms) through a half wave SCR circuit. a. If the SCR is triggered at 90 degrees, calculate the angle at the maximum instantaneous current.
A 100-watt motor (60% efficient) is used to raise a 100-kilogram load 5 meters into the air. If the task takes 65 seconds to complete, how heavy was the load in units of kilograms
A dc motor takes an armature current of 105 A at 480 V when running at 720 rpm . The resistance of the armature circuits is 0.2 Ω and the field resistance is 96 Ω what is the torque developed in the armature
There is some interest from industry to be able to track the solidification or drying of the paint layer as it happens to ensure correct thickness and material properties. One way to do this would be to measure the changing values of the permittiv..
The flat circular disk rotates about a vertical axis through O with a slowly increasing angular velocity ?. Prior to rotation, each of the 0.44-kg sliding blocks has the position x = 22 mm with no force in its attached spring.
how many decimal numberes can be represented by 10-bits. what is the largest unsigned decimal number that can be represented by 10-bits.
A function f has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Derive the truth table for f. (b) Write the canonical sum-of-products expression for f.
