For the Y-Y circuit in Practice Prob. 12.2, calculate the complex power at the source and at the load.
Practice Prob. 12.2
A Y-connected balanced three-phase generator with an impedance of 0.4+j0.3 Ω per phase is connected to a Y-connected balanced load with an impedance of 24 + j19 Ω per phase .The line joining the generator and the load has an impedance of 0.6 + j0.7 Ω per phase. Assuming a positive sequence for the source voltages and that
, find:
(a) the line voltages,
(b) the line currents.
What is the frequency for a periodic signal with a period of 2.5 ns 2.5 GHz 250 MHz 4.0 GHZ 400 MHz 2. Which decimal number is equivalent to 25 10 25 31 32 3. Convert the following decimal negative numbers to their 8-bit, 2's complement formulatio..
1 you will create a data set consists of the total data number elements. for example if your total data number is 127
discuss the difference(s) and similarity(ies) between the modulations index used in AM and the modulation index used in FM What are the practical interpretations
The output voltage should be 5 V, but is ~1.25 V. This output voltage is independent of the power supply voltage. That is, no matter how high or low I set the power supply voltage, the output voltage is ~1.25 V as long as the input voltage is 50 mV.
Suppose an object with initial acceleration of 10 ft/s^2 is dropped from 300 ft. above the earth, how far would it travel in the first 2 seconds of its journey. Assume initial velocity is zero.
Design an ionospheric radio link over a distance of 2500 Km given that the ionosphere effective height is 275 Km and the electron density N= 2*1011 /m3, namely find : i- the angle of incidence on the ionospheric layer.
where fc is the carrier frequency, Ac is the carrier amplitude, µ is the modulation index, and x(t) is the baseband message signal. We assume that x(t) has absolute bandwidth W
Determine the FWHM diameter of the beam 50 mm from the second lens (ie. 100 mm from the first lens.) A third lens is placed at the point with a focal length off.
A composite load consists of 3 loads connected in parallel.Onedraws 100W at a power factor of .92 lagging, another takes 250W ata PF of .8 lagging, and the third requires 150W at a unity PF.The parallel load is supplied by a source Vs in series wi..
Even if a man shows no visible perspiration he still evaporates about 500 grams of water per day from his lungs. How many calories of heat are removed by this evaporation? What is the rate of heat loss in watts due to this process?
Given a sum-of-products expression, it is possible to write the 1s corresponding to each product term directly on the map without developing an explicit truth table of minterm list, and then proceed with map minimization procedure.
If we define the resolution of a Digital-to-Analog Conversion (DAC) device to be the reciprocal of its number of logic states in percentage, what will be the resolution of an 8-bits DAC device
