Suppose that a three-bus power system has the subtransient bus impedance matrix given below, and that the power system is initially unloaded with a pre-fault bus voltage of 0.98 pu. Assume that a symmetrical three-phase fault occurs at Bus 1, and find:
(a) The current flowing in the transmission line from Bus 2 to Bus 1 during the subtransient period.
(b) The current flowing in the transmission line from Bus 3 to Bus 1 during the subtransient period.
An LED is connected to a 74LS244 in an active-LOW configuration. The key parameters for the 74Ls244 are IOH=-15 mA, IOL=20 mA, VOH =2.0V and Vol=0.5V. The LED has a voltage drop of 2.0V and an operating current of 15 mA.
What is the shape of the spectrum of the signal? What is the extent of the spectrum in the frequency domain? What is the unit that is applied to the magnitude of the spectrum?
• Explain the difference between an AC induction motor and an AC synchronous motor. Include in your discussion the differences in motor construction and torque-operating characteristics.
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms, calculate mmf when the machine operates at rated voltage.

In the 3-Op Amp Instrumentation amplifier, all the resistor values are the same with the exception of RG which determines the gain. Is it possible to have additional gain at the output Op Amp of Rf/Rin
The electric field intensity of a linearly polarized uniform plane wave propagating in the +z direction in seawater is E= 100 cos(10^(7) pi*t) V/m at z = 0. constant of emissivity = 8.854 * 10^(-12) F/m
1. The net charge through a cross section of a circuit element is given by q(t)=2t+t^2 C. As usual, t is in seconds. Find the current through the element in amperes. 2. the current through a given circuit element is given by i(t)=2e^-t A. As usual..
Write the VHDL assignment operator for the Y1 output of a BCD-to-binary encoder. Use Boolean operators, D0-D9 as the data inputs lines and Y0-Y2 for the outputs. Inputs and outputs are active-HIGH.
