Fifteen castings of a certain type are produced per day in a foundry. The finished castings are inspected and classified as defective or non-defective. Records indicate that of the last 500 castings inspected, 16 were defective. Based on this information, find the following:
(a) The probability of having at no defective castings in a day's production
(b) The probability of having at least two defective castings in a day's production
A 277/480V three phase wye system has the following load: M1- Induction Motor, 50hp, n=0.91, PF= 0.89 at full load. M2- Induction motor, 25hp, n=0.9, PF= 0.9 at full load. R- Heater Load, PF=1 M- A synchronous motor to drive a second 25hp load.
what is the range of sampling frequencies you can use such that you don't violate Nyquist theorem and still meet or exceed the needed resolution when you perform the FFT operation on the full set of collected data
The transfer function of a particular active low pass filter is G(s) = 200/[s(1+0.4s)(1+0.1s)]. a) At a frequency of 1.0Hz it is determined that the gain of this filter in dB b) Find the phase shift in degrees through the filter as the frequency appr..
an amplifier with an input resistance 10kohm, when drieven by current source 1microA and a source resistance 100kohm has a short circuit output current of 10mA and an open circuit voltage of 10 V. The device is driving a 4kohm load.
Physically test your design in the FPGA development board. Use two switches to produce rst and ena and use an LED to display the output.
The rotor of a 3phase, 5kw, 400v, 50Hz, slip ring indution motor is wound for 6 poles while its stator is wound for 4 poles. The approx average no load steady state speed when this motor is connected to 400v, 50Hz what is the supply
Write a program that counts the number of characters in a text file. Write a program that count the number of words in a text file. Write a program that counts the number of lines in a text file.
The available powersupply voltages are VCC = 15 V andVEE=-15 V. Maximize |Avs| in a manner consistent with the otherspecifications. Use SPICE to find the midband gain and the upperhalf-power frequency for your design.
An LED is connected to a 74LS244 in an active-LOW configuration. The key parameters for the 74Ls244 are IOH=-15 mA, IOL=20 mA, VOH =2.0V and Vol=0.5V. The LED has a voltage drop of 2.0V and an operating current of 15 mA.
If the earth is considered to be a metal sphere(radius˜6371[km]), how much charge Q must bedeposited on its surface in order for an arc to be established inthe air. If the earth's surface was charged to the value byremoving all the electrons from ..
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms
Consider a step-down transformer with 15 turns in the primary and 6 turns in the secondary windings.Calculate the input impedance of this transformer loaded to an 8 O resistor, assuming that series resistances of the windings are negligible.
