A 600V, 150hp, DC series motor operates at it's full-ratedload at 600 RPM. The armature resistance is 0.12 ohms and theseries field resistance is 0.04 ohms. The motor draws 200A at full load.A) Determine the armature voltage Ea atfull-load. B) Determine the armature-developed power Pdev and intenal-developed (induced) torque in Nm. C) Assume that a change in load results in the line currentdropping to 150A; determine the new speed in RPM and the newdeveloped torque Tdev .
the following binary numbers are all represented using 6 bit signed 2's complement. all addition should also be conducted in 2's complement form. A=111000; B=010110 (a) what is A's value in decimal
A copper wire has a diameter of 2.05 mm and carries a current of 5 A due solely to electrons. (these values are common in residential wiring.) Each electron is has a charge of of -1.6 × 10-19 C.
A motor with efficiency of 76% supplies 20 hp to a load. it's power factor is 0.6 (lagging). A voltage of 440 VAC (RMS), 60 hz is applied to the motor. a) what is the real power applied to the motor in Watt
Thickness is to be reduced in three steps in a hot rolling operation. Each step will reduce the slab to 75% of its previous thickness. It is expected that for this metal and reduction, the slab will widen by 3% in each step.
Write C code that senses 3 accelerometer readings into pins PAD 8, 9 and 10 and displays them on the LCD. Also run a timer in seconds and log the values of the accelerometers in 3 arrays every second.
For each of the following functions, put the equation in the form of a Shannon decomposition. Create a pass transistor schematic to implement the function. Count the number of NMOS and PMOS transistors and the number of inverters.
a. Implement both functions with one 3:8 decoder and logic gates. b. Implement both functions with one or more 8X1 muxes (and logic gates if needed) c. Implement both functions with 2X4 decoders and logic gates.
Write a MATLAB program that will allow a user to type the specific heat of a value in calories per gram degree Celsius. Display the converted value in units of British thermal units per pound-mass degree Fahrenheit in the Command Window
design a new p-type semiconductor material. Acceptor density is Na=5x1015 cm^-3 and there are no donors are present in the material. The effective densities of states for this material is given as Nv=1.8x10^19cm^-3
Interpreting frequency domain signal spectrum to time domain, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the voltage level of signals in volts vertically and frequency horizontally.
Given a parallel RC circuit with input voltage Vs, resistance value of R, capacitance value of C, and Vo taken across the capacitor. For this circuit, Vo/Vs=1/(jwRC+1), so the gain is 1 V/V. Is there any way to modify this circuit to make the gain..
