An isolated 75MVA synchronous generator feeds its own load and operates initially at no-load at 3000 r.p.m., 50 Hz. A 20MW load is suddenly applied and the steam valves to the turbine start to open after 0.5 s due to the time-lag in the governor system. Calculate the frequency to which the generated voltage drops before the steam flow meets the new load. The stored energy for the machine is 4 kWs per kVA of generator capacity.
Three identical impedances of (12+j15)ohms are connected in wye to a 550V balanced three phase source. Determine, (a)the magnitude of the line currents. (b) the total power dissipated for the three phases. (c)the total reactive power. (d)the power..
Consider a Si p-n junction at room temperature. If the doping concentrations are NA=1016 cm-3 and ND=1015 cm-3, what is the depletion width also known as space charge width. Also find the maximum electric field.
Make a plot of group velocity versus frequency for frequencies from 0 Hz to 500 kHz. Your plot should have 3 different curves for the three modes of propagation. Be sure to identify the modes and all cutoff and resonant frequencies clearly.
consider a message signal m(t)= e^(-2t) cos(2000*pi*t) u(t) a) determine the minimum step size E necessary to avoid slope overload b) calculate the minimum avaerage quantazation noise power based on part a
Write an equation relating the donor-atom concentration, the acceptor-atom concentration, the free-electron concentration, and the hole concentration for a doped semiconductor.
In an AC generator the magnetic field is .05T, the number of loops is 12, the operating temperature is 90degC, the rotational speed is 50cps, the power factor is .96 leading and the are enclosed by one loop is 2 sqft.
a single silicon photovoltaic cell is found to have an open-circuit voltage of 0.6 v and a short-circuit current of
Use the map template to create a phone list for a department. Their should be 10 people in the department. The map will use the person's first name and telephone number. Enter individuals in an unsorted order and then list the persons based on the..
what size capacitor should be placed in series with the series combination of 800 ohms and 20mH to give an admittance whose magnitude is 1m/ohm at w=10k rads/s
