A 500 kVA, 600 V, 0.8-PF-leading, Y-connected synchronous motor has a synchronous reactance of 1.0 per unit and an armature resistance of 0.1 per unit. At the current time,
(a) Is this machine currently acting as a motor or a generator?
(b) How much power P is this machine consuming from or supplying to the electrical system?
(c) How much reactive power Q is this machine consuming from or supplying to the electrical system?
(d) Is this machine operating within its rated limits?
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 12-V automobile battery has an output capacity of 100ampere-hours (Ah) when connected to a head lamp that absorbs 200watts of power. a) Find the current supplied by the battery.
On the other hand, when S is high,we should have O1 = I2 and O2 =I1. Thus, S acts as the control input for a reversingswitch. Use Karnaugh maps to obtain a minimal SOP(sum ofproduct) design. Draw the circuit.
mesh analysis involves writing and solving a number of simultaneous equations. The number of equations is equal to the number of independent loops in the circuit. Each equation is derived from the application of KVL around the loop.
A D'Arsonval meter movement is described by its fullscale current Ifs and full scale voltageVfs , with Vfs= 100mV andIfs=10mA . Determine the resistanceRm of the D'Arsonval meter movement.
Efficiency in a power transformer is 98.6 percent when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
If a linearly polarized wave is propagating in this material, what is the distance it must travel in order that its polarization is rotated 90??
1. For a triangular waveform, with a peak amplitude of 2V, a width of 10ms, and a period of 10 ms a. Draw the waveform. b. What do you think the average value will be for this waveform. c. Determine the average value - was it wh..
Consider a linearly graded Si p-n junction. Find a relation for the potential across the depletion region. Hint: Start from equation 29 in chapter 3 of the text book. Integrate the electric field to find the potential.
Implement this machine using the pointer-based technique and VHDL or SystemVerilog. Start by making the proper adaptations (using pointer(s)) in the state transition diagram. Create an array of constants to be placed at the output in states B and ..
Show by means of a drawing what happens if the charge is moved from the center plane toward the upper plane so that it is at a distance b from the upper plane and a distance c from the lower plane while the radial distance is maintained (point B).
The highest frequency contained in a certain analog signal is 4 kHz. Determine the sampling rate if it is chosen to be 50% greater than the theoretical minimum.
