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
Each single phase transformer has an identical number of turns in the primary and secondary windings. If a line-to-line voltage of 480V is applied on the wye windings, compute the line-to-line voltage on the delta windings.
What is the purpose of a state diagram, and what information can we derive from it. What is the major differences between an asynchronous counter/divider and a synchronous one.
If point charges of value +2[nC] are located at the pointsP1(2,2,-1)[m]and P2(1,-2,1)[m],respectively, find the voltage Vab betweenpoints Pa(2,3,1)[m] and Pb(-1,2,2)[m] by using superposition principle and the potential expression for point charge..
1. Let Vi has a peak of 10v and R=1kOhm. Find the peak value of id and DC compoent V-o. 2. Consider a silicon diode with n = 1.5 Find the change in voltage if the current changes from 0.1 mA to 10 mA.
A diode is measured to pass 0.31mA at 0.70V forward bias, and 1.12mA at 0.75 V forward bias. What are its n and Is. Assume that kT/q=0.026V. For extra credit, if the diode passes 4mA at 0.9V forward bias, what is its forward parasitic resistance
What is frequency sensitivity of the demodulator? What is the value of A_m for which the carrier component is reduced to zero for the second time
How much electrical charge is needed to raise an isolated metal sphere of radius 1.0 m to a potential of 1x10-6 V
Suppose the z=0 plane carries a sheet current K=5. A/m x. Then a 1 m long rod exists above the current sheet and has velocity u. Find the Vemf when the rod is parallel with the x-axis, u= 2(m/s) y.
The serial ports on two computers which use binary signaling are connected by a twisted pair cable. The cable has a flat frequency response up to 120KHz, with negligible group delay distortion. That is, the bandwidth of the cable is 120KHz.
A M-bit thermometer code for the number k consists of k 1's in the least significant bit positions and M-k 0's in the more significant bit positions. A binary-to-thermometer code converter has N inputs and 2^N-1 outputs.
The signal x(t) consists of sum of two components, x1(t) and x2(t). The signal x(t) is bandlimited to 40 kHz, and it is sampled at a rate of 100 Khz to yield the sequence x(n). It is desired to suppress the signal x2(t) by passing the sequence x(n) t..
A rectangular loop of wire containing a high resistance voltmeter has corners initially at (a/2, b/2, 0), (-a/2, b/2, 0), (-a/2, -b/2, 0) and (a/2,-b/2, 0). The loop begins to rotate about the x axis at constant angular velocity w.
