How does the speed of an induction generator relate to synchronous speed Explain. How is power factor could be controlled if is is a squirrel cage machine? How about a wound rotor machine
A charge density of ohm Coulombs per square meter is uniformly distributed over a thin and very long cylindrical shell of radius a. You want to know the electric flux density field D and the electric field E generated by this charge at all points ..
A) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end, calculate the voltage at the transmitting end. B) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end
A CS amplifier using an NMOS with gm = 3.8 mA/V is found to have an overall voltage gain of -16 V/V. What value should a resistance RS inserted in the source lead have to reduce the overall voltage gain to -8 V/V
Write an equation to help determine P-type body doping concentration Na for a required threshold voltage V (sub TN) for an N-channel Al-Sio(sub 2) -Si MOSFET. Use the equation to design an N-MOSFET with a thershold voltage of 10V
Research the recent history of gasoline pricing in your area, and attempt to relate any fluctuations you observe to documented supply and demand factors outlined in our book. Be sure to cite any references used.
(a) Compute the minimum voltage that the output voltage across R1 falls to when both capacitors C1 and C2 are present. (b) Using the same model for D1, compute the maximum voltage that the output voltage across R1 rises to.
The continuous-time sinusoid x(t) = cos(300?t) is sampled every Ts = 2.0 ms, so that x[n] = x(0.002n) For what other values of f in the range 0 Hz to 2.0 KHz does the sinusoid v(t)
First you must give all different possible connection types for them and then, for each case, you should develop some tests that can define the connection type and calculate the current passing through the capacitors.
1.For an impedance equation, such as 15ohms + j60ohms, explain the steps to determine equivalent series and parallel circuits. 2.For a given parallel RC or RL circuit, explain how admittance, current, and phase would change
Instantaneous voltage and current of capacitor, The current flowing through a 5 F capacitor is i=3e^-2t. What is the voltage as a function of time, if the initial voltage is zero?
