For random ergodic voltage signal, I make a histogram of sample voltages and note that they form a Gaussian distribution. estimate the following moments over a number of samples taken at diffrent time points alont the voltage signal:
Mean Value: mv=0.5VStandard Deviation: ov=0.2V
Determine these signal parameters: DC voltage, AC power, and Total power.
Assume a 1 ohm load for the purposes of computing power in watts.
The electrostatic potential in space is given by the scalar field V(r)=V(x,y,z)=e^y + (3x)^2-4cos(z) Find the potential difference between the points P(1,1,1) and Q(0,0,0).
Calculate the de Broglie wavelength of the following: A proton with kinetic energy of 1 M eV.
A 415V to 11 kV transformer has a rating of 200 kVA. The winding resistance and leakage reactance when referred to the primary are 0.014 and 0.057 ohms respectively.
A micrometer caliper is used to measure the diameter of a bolt and a reading of 0.768 inches is obtained. Based on this measurement, find the smallest possible diameter and the largest possible diameter.
One reason that the maximum electric field is important is because of the possibility of impact ionization, which may be desired or undesired in a particular application. The process of impact ionization is dependent on the electric field
A single phase 1750 RPM moter operating at rated power has a power factor of 0.75 lagging. the line voltage is 208 VAC @60 Hz and the line current is 27A. Assuming 83% is a reasonable efficiency for moters of this size
Identify the bus types and the unknown variables of the power flow problem. Write the complete set of equations needed to solve the load flow problem.
1- If the diameter of a spherical water droplet is 100.0 µm, how much energy is required to increase the diameter of the water droplet by 3.0 µm The surface tension of water is 1.0 x 10-3 J/m2. 2- A metal crystallizes in a face-centered cubic lat..
What are the positive and negative implications of wireless energy?
A typical method of measuring the linearity of an amplifier is called the "Two-tone" test. Signals at f1 and f2 are input to the amplifier and the output spectrum is observed. Assuming that signals at 14.1 and 14.2 MHz are input to an amplifier.
A three phase, 25-hp, 440-V, 60-Hz, 1750 rpm, wound-rotor induction motor has the following equivalent circuit parameters:R1=0.20 ohms, X1=1.0 ohms, R2=0.15 ohms, X2=0.8 ohms, Xm=30 ohms The motor is connected to a three phase, 440-V, 60-Hz supply.
Design and implement a Rectangle class. Make your class inherit from the Point class given in the lecture (notice that a rectangle can be described through the upper-left vertex, the height, and the width).
