A 3-phase power system consists of a wye-connected generatorconnected to the following loads, which are in parallel, through atransmission line. Load 1: Wye-connected load that consumes atotal 3-phase power of 3.6 kW at 0.8 power factor lag, when the generator voltage is set so that the voltage at the load is 480volts line-to-line. Load 2: Delta connected load that consumes 2kW+ j1 KVAR of power. The transmission line has an impedance,Zline = 1.2 at angle 60 degrees ohms per phase.a) Determine the total complex power consumed by these two loads. b) Determine the line current magnitude and phase angle.c) Determine the magnitude and phase angle of the line-to-line voltage at the generator
Design and model a car battery charger using PSpice. Suppose that the source is a commercial circuit of 240V AC at 60Hz. The battery to recharge is 12V DC.
(b) Find and list all essential prime implicants of the F function. (c) Find the minimal two level NAND gate implementation of the F function. Find the gate input cost. (d) Find the minimal two level NOR gate implementation of the F function. Find th..
A three-point symmetric moving average filter, referred to as a weighted moving average is of the form \(y[n]=b(ax[nu22121]+x[n]+ax[n+1])\) (a) Determine as a function of a and b the frequency response \(H(e^{j\omega})\) of this system.
An aluminum casting that has a mass of 10 kg sits on a steel surface. How much force will be necessary to get it to start sliding. The static coefficient of friction (mu) for aluminum on steel is 0.61.
In a 50 mm diameter x 0.5 mm thick wafer of pure germanium at room temperature, (a) how many conduction electrons would be present, and (b) how many electron holes would be present.
Let real periodic sequence x[n] have Fourier Series coefficients ak and sequence y[n] have coefficients bk. Both sequences are periodic with period N = 8. If bk=((-1)k+2ak-2 write an expression for y[n] in terms of x[n].
A circular polarized wave in air is incident on glass surface. The angle of incidence equals the Brewster angle. Refractive index of glass, n(glass) is 1.35. Find the following quantities: 1) The Brewster angle. 2) The angle of refraction 2.
A belt is wrapped around a pulley creating a torque of 186 N-m. What power is being transmitted if the pulley is rotating at 200rpm
spring stretches by 0.0186 m when a 3.24-kg object is suspended from its end. How much mass should be attached to this spring so that its frequency of vibration is f = 5.53 Hz
why there is no earthing in television, rather it is a very complicated and its plug is always 2 pin. On the other hand mobile charger has got 3 pin plug and therefore earthing is done in it while charging of mobile.
construct a vertical line on your I versus V graph at the point V=5V. this line will intersect each of the sloping lines at two separate points. explain the significance of these intersections.
Capture the following system behavior as an HLSM. The system counts the number of events on a single bit input B and always outputs that number unsigned on a 16-bit output C, which is initially0. An event is a change from 0 to 1 or from 1 to 0.
