You have a 120 VAC motor pump system. The system will work in a voltage range from 100 to 130 volts. you can count on the minimum voltage from the supplier to be 115 VAC. The wiring will consist of #14 awg which has a resistance of 2.5 ohms/1000 feet. The pump is slightly over 1000 watts.
What is the maximum distance between the pump and the power source?
A 1500 hp phase ac motor load has a power factor of 0.7. What capacitor (in Farads) is required to correct the power factor to 0.90 if the line voltage is 2400 volts The capacitor bank is to be delta connected.
Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.

Electrical wiring: Potentials of neutral and earth wires, Why is the neutral wire in housing circuits also at zero potential
An engineer decides to take 600 samples at sampling frequency 9000Hz. A Fast Fourier Transform (fft) program was applied to obtain the frequency spectrum of the signal. What is the frequency resolution,df, for the analysis
HCI is a polar molecule, with a dipole moment of 3.44 X 10^-30 [C.m] per molecule. If it is known that the molecular bond distance is 0.136[nm], find the magnitude of the net displaced charge in each molecule.
The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
Design a circuit with output f and inputs x1, x0, y1, and y0. Let X=x1x0 and Y=y1y0 represent two 2-digit binary numbers. The output f should be 1 if the numbers represented by X and Y satisfies X>=Y
