3-phase line, which has an impedance of 2 + j4 per phase, feeds two balanced three-phase loads that are connected in parallel. One of the loads is Y-connected with an impedance of (20 + j40) per phase, and the other is -connected with an impedance of (65-j40) per phase. The line is energized at the sending end from a 60-Hz, three-phase, balanced voltage source of 120 (3)^1/2 V (rms, line-to-line).
Determine:a) The current, real power, and reactive power delivered by the sending-end source. b.) The line-to-line voltage at the load. c) The current per phase in each load. d). The total three-phase real and reactive powers absorbed by each load and by the line.
The axis of the cylinder is along the z axis, and the electrons are moving with a velocity vector v in the positive z direction. The velocity of the electrons is 0.1c where c is the speed of light (2.99792458 ´ 108 [m/s]). The magnitude of the cur..
Restricting yourself to nondegenerate dopings and also requiring the resistance to be readily measured with a hand-held multimeter (say 1 R 1000), what is the range of doping Pick a doping concentration in the mid range.
Implement a high-speed multiplier which will multiply two 2-bit binary numbers (B1B0 and C1C0) using a 16X4 PROM (lookup table implementation). List the content of all the memory locations in the PROM and describe the operation.
The simple inexpensive hydro turbo-generator (turbine mated with electric generator) that you intend to buy has a working efficiency of 60%. Answer the following (show your work).
1. An SEdit schematic showing a properly constructed complex CMOS gate of your function. 2. Annotate the schematic with proper sizing parameters for each transistor to achieve behavior similarto a symmetric inverter
The open circuit test on a single-phase 15kVA, 7500/480 V, 60 Hz distribution transformer yielded the following: V = 7500V; I = 0.2006A; P = 180W Calculate the core parameters RC and XM and the magnetizing current IM.
average velocity of v meters/second. If the concentration of free electrons is 10^{29} electrons per cubic meter and if they are uniformly dispersed throughout the wire, then what is the average velocity of an electron
why does the instruction set include an INC (DEC) instruction to increment (decrement) a memory byte when the same function could be accomplishe using an ADD (SUB) instruction
one question: During each cycle, the velocity v (in mm/s) of a piston is v = 6t - 6t^2, where t is the time (in sec). Find the displacement s of the piston after 0.75 sec if the initial displacement is zero.
A fluid flows through a turbine at the rate of 45 kg/min. Across the turbine the specific enthalpy drop of the fluid is 580 kj/kg and the turbine loses 2100 kj/min in the form of heat energy. Determine the power produced by the turbine.
Find the system transfer function of a causal LSI system whose impulse response is given byh[n] = (-0.5)^n-1 sin[0.5(n-2)]u[n-2] and express the result in positive powers of z. Hint: The transfer function is just the z-transform of impulse respon..
