Three single-phase transformers are connected in a wye/delta configuration. Each single-phase transformer has an identical number of turns in the primary and secondary windings.If a line-to-line voltage of 480V is applied on the wye windings, compute the line-line voltage on the delta windings.
Analysis of discrete time waveforms in z domain, A discrete time domain signal x(n) - u(n) - u(n-10) is decomposed and plotted. It is then examined in the z domian by appropriate transformation and algebraic manipulation.
Find the dimension of the window, as measured at the top of the oxide, after ideal isotropic etching (i.e. no overetch). Draw a cross section of the window opening with the resist still on.
A 11 GHz uniform plane wave with maximum electric field of 100 V/m propagates in air in the direction of a x-direction. The magnetic field has only a a(z) component ( in the z direction), which is approximately equal to 100 mA/m at x = y = t = 0.
A charged 100- picoFarad capacitor has initial voltage across it of 10 V. A 100 kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec
3-singlephase 2 winding transformers, each rated 500 MVA, 13.8/199.2 kV, with leakage reactance Xeq = 0.10 per unit, are connected to form a three-phase bank. Winding resistances and exciting current are neglected.
Calculate the lowest 3 energy levels in a quantum well made from InAs, using the infinite potential approximation. Length of the well L = 10 nm.
A voltage source 100(angle 0 degrees) is in series with a 200 ohm resistor and a cpacitive reactance of -100 ohms. a) What impedance,Zl, in parallel with the capcitor would absorb maximum AVERAGE power
Plot the reflection coefficient for 4 pairs of quarter-wave coated substrate for acrylic/diamond coating-pairs on fused silica substrate. Your plot should be as a function of wavelength range from 400 nm to 1 micrometer.
After a package is ejected from the plane, how long will it take for it to reach sea level from the time it is ejected Assume that the package, like the plane, has an initial velocity of 200 mph in the horizontal direction.
A sinusoidal voltage has a maximum value of 100V, and the value is 10V at t=0. The period is T=1ms. Determine the angular frequency, w, in rad/sec.
When the temperature is held constant, the digital display of thermometer A does not change, but the display of thermometer B randomly toggles between three to four adjacent readings (i.e., +/- 2 degrees). For the questions below, assume that the ..
Find the electric field intensity at (0,0,75000) produced by 50,000 0.1 C charges along the x-axis spaced at 1 meter apart starting at (1,0,0) and 50,000 0.2 C chargers along the y-axis spaced at 1 meter apart starting at (0,1,0).
