Suppose the z=0 plane carries a sheet current K=5. A/m x. Then a 1 m long rod exists above the current sheet and has velocity u. Find the Vemf when the rod is parallel with the x-axis, u= 2(m/s) y.
Explain the characteristics of electromagnetic waves and application to communications systems and determine the signal spectra for the content of complex waveforms
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
What is the conversion efficiency of an amplifier in which the effective value of the current through a 2.2-k? load is 5 mA and the drain on the 18-V dc supply is 3.8 mA
Voltage, current, power, and stored energy of capacitor, Prior to t=0, a 100- uF capacitance is uncharged. Starting at t=0, the voltage across the capacitor is increased linearly with time to 100V
Derive the dynamic model and average value circuit of a buck converter assuming the ESRs of the inductor and capacitor are not equal to zero.
An early code used in radio transmission involved using codewords that consist of binary bits and contain the same number of 1s. Thus, the 2-out-of-5 code only transmits blocks of 5 bits in which 2 bits are 1 and the others 0.
A certain power amplifier with crossover distortion has the input/output voltage relationship vo (t) = vi (t)3 (2.39) a) Use example voltage values to show that this does not satisfy the relationship. b) Let vi (t) = sin (pi t) .
Calculate the probability that the system will fail in 3,000 hours. Supposing no failure of any component occurs in 5,000 hours of operation. What would be your revised estimate of failure rates of the components in your system?
a road between fairbanks and nome, alaska, will have a most likely construction cost of $4 million per mile. doubling this cost is considered to have a probability of 30%, and cutting it by 25% is considered to have a probability of 10%.
Explain why the short-circuit method for determining the Thevenin resistance of a circuit cannot be applied if the circuit does not contain any independent current or voltage sources.
A long straight metal wire of radius r1= 2.20E-2 m is surrounded by a metalic cylindrical shell of inner radius r2= 1.24E-1 m and outter radius r3= 1.91E-1 m. The axes of the wire and the cylindrical shell coincide.
a plane wave is obliquely incident onto the planar interface between mismatched, lossless, nonmagnetic, uniform media, yet undergoes no reflection. If incidence is at 54 degrees to the normal, at what angle to the normal does the transmitted wave ..
