An industrial load is connected across a three-phase, Y-connected source of 4.5 KV (line-to-line). The real power of the load is 160kW, and its power factor is 0.8 lagging:
a. Compute the reactive power of the load.
b. A synchronous motor is connected across the load to improve the total power factor to unity. The synchronous motor is running unloaded (no mechanical load). If the synchronous reactance of the motor is 10Ω, compute the equivalent field voltage of the motor.
A temperature sensor measures from -44 f to 212 F with an output of 0-5 v. If an 8 bit ADC is used, what is the converter output for a temperature of 25 F
Do this using for loops. For your first prompt you will enter the number N of integers that will follow, then you will be prompted for each integer. Compute the sum and average and provide the output. Do it 3 times using the Matlab, Python, C++
Describe what happens in terms of set point, feedback signal, error signal, and arm position.
A receive antenna located at 1km from the transmitter has a gain of 5dBi. Assume that there are 2dB of system loss.A. If the system operates at 900MHz, what is the power level at the output of the receive antenna terminals
The current distribution on a center-fed short dipole (length l n ë) centered at the coordinate origin and lying along the z-axis can be written as where Io defines the peak value of the current at the feed point of the antenna.
If the slip is 5%, determine (a) the rotor copper loss, (b) the total mechanical power developed by the rotor, (c) the output power of the motor if friction and windage losses are 750 W, and (d) the efficiency of the motor, neglecting rotor iron l..
Obtain the z transform and find the z transform - solve the problem for the first 30 samples. Plot both analytical and the numerical results in the same figure.
If a particular radar reciever can detect the target using HH polarization at a maximum distance of 10km, find the maximum distance at which the target can be detected using VV polarization. Assume a standard radar equation.
For a given circuit in fig. , find out the equivalent resistance between X and Y.
What is the maximum quantization error for a signal that is quantized to peak-to-peak amplitude of 3V and using 7 bits. Think of quantization error as the difference between the actual sample's value and the value you assign it from quantization.
The signal m(t)=6sin(2*pi*t) volts is transmitted using 4-bit binary PCM system. The quantizer is of the midriser type, with a step size of 1v
Obtain the discrete-time (DT) or sampled signals x[n] = x(nTs) and h[n] = h(nTs) by discretizing the CT signals x(t) and h(t), respectively, using a sampling period of Ts = 0.01 s. This value ensures that the two CT signals can be fully recovered,..
