A synchronous generator connected directly to an infinite bus is generating at its maximum real power. The line-to-line voltage of the infinite bus is 480V and the synchronous reactance of the generator is 5Ω. Compute the reactive power of the generator.
Derive the expression for the friction torque in ?at collar bearing considering uniform pressure and uniform wear.
A continuous-time signal x(t)=cos(2πt) is sampled every T seconds, resulting in a discrete-time signal x[n] = x(nT) . Determine whether the sampled signal is periodic and if the signal is periodic, determine the number of samples in the fundamenta..
Let X denote the number of accepted circuits. Let Y be a random variable which is 1 if the last (Nth ) IC was accepted and is zero otherwise (it is a Bernoulli random variable). (a) Write out the probability mass function (PMF) of X.
A sheet of aluminum foil has a thickness of about 1 mil (a mil is 0.001 inches). Calculate the dB of attenuation of a plane wave that goes through the sheet of aluminum foil, at a frequency of 2.45 [GHz]. Is the sheet of aluminum foil a good shield f..
1. Calculate the frequency for each of the following periods:
Sketch the phasor diagrams for the following waveforms: v1 = 80sin(pi*t + 35°)(a) What is the phase difference between v1 and v2 (b) Determine which voltage leads and which lags.
An analog signal consists of three sinusoids with frequencies3.1 KHz, 4.82 KHz, and 5.64 KHz. The signal is sampled at asampling rate of 32 KHz producing the Discrete signal x(n). Determine the normalized frequencies in x(n).
Consider a balanced three-phase system where the sources areconnected in a wye formation and the load is connected in a wyeformation with impedance ZPY for each phase. The"a" phase source voltage isVan=220
A star connected synchronous motor at 187 kVA, 3-V, 2300V, 47A, 50Hz, 187.5 rpm has an effective resistance of 1.5 ohm and a synchronous reactance of 20 ohm per phase. Determine internal power developed by the motor when it is operating at rated c..
