A 60-Hz source supplies power to an industrial load through a transmission line of impedance (0.2+ j0.1) ohms. The load consumes 130 kW of power at line voltage VL= 440<10° V rms VL and power factor 0.78 lagging.
(a) Propose a power factor correction scheme for improving the power factor at the load.
(b) Implement the power factor correction scheme in part (a) so that the new power factor at the load is raised to 0.9 lagging.
assume QPSK is the modulation method used in a digital communication system.The communication system requires minimum bit error.what is the acceptable bit error assuming additive white gaussian noise.
A single-phase, half-wave SCR circuit is used to control the power consumption of an inductive load. The resistive component of the load is 5 Ohm. The source voltage is 120 V (rms). When the triggering angle is adjusted to 60 degrees
Two machines and a lighting load are connected in parallel to a 240 V(rms), 60 Hz line. The first machine uses 230 kW of power at 0.85 power factor lagging. The second machine uses 95 kVA at 0.882 power factor leading. The lightening load consumes..
a.) What isthe minimum sampling frequency to avoid aliasing b.)If the sampling frequency of fs=2500 samples/sec is used how many samples must be taken to give a frequency resolution of 10Hz
Inflation in years 1-5 equals 3.1 percent, 2.2 percent, 1.6 percent, 1.3 percent, and 1.1 percent, respectively.
The voltage across the load must remain between 4.7 and 5.0 V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available.
Explain the characteristics of electromagnetic waves and application to communications systems and determine the signal spectra for the content of complex waveforms

A mixture consisting of 0.100 mole N2, 0.050 mol O2, 0.200 mole CH4, and an unknown amount of CO2 occupied a volume of 11.1 L at 27°C and 1.00 atmpressure. How many moles of CO2 are there in this sample
the output voltage of battery drop from 6V .With no load to 5.2V with a load current of 400mA. calculate the internal resistance.
Transfer function : key informaiton, A linear time-invariant discrete-time system is excited by the input x[n] = d[n] + 2u[n-1] (d represents δ(delta)). The resulting output response with zero initial conditions is y[n] = ((0.5)^n * u[n]). De..
