A 120 V, 60Hz source is connected to a distribution line whose resistance and inductive reactance is .001 Ohm and j0.002 Ohm respectively. A single phase, 100 HP, 120V, 0.85pf motor and a 100 kW, 120 V Heater are connected in parallel. Find:
*The value of a capacitor connected in parallel to improve the pf to unity (pf=1)
*Current flowing in each olad before connecting the capacitor and after connecting it.
*Total impedance of the circuit before connecting the capacitor and after.
*power factor of the source before connecting the capacitor and after connecting it.
*power consumed by the load before connecting the capacitor and after connecting it.
* line losses before connecting the capacitor and after connecting the capacitor.
Several copies of the signal, shifted in time and frequency as well as attenuated, are received-that is, the transmission is done over multiple paths each attenuating and shifting the sent signal. The sum of these versions of the signal appears qu..
A charged 100-pf capacitor has initial voltage across it of 10V. a 100kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec?
A 1000-μF capacitor is fully charged to 10 V. What is the amount of charge stored in the capacitor. How much energy isstored.
An ND:YAG laser in the lab emits light at 1064 nm. The laser is light is directed into a slab of silicon, which has an index of refraction n = 4. a. What is the relative permittivity of Si at this wavelength (Hint: Si is non-magnetic.)
Open Neutral Assume that the load is star connected with the neutral disconnected. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Plot the neutral voltage Plot the phase to neutral voltage for phase a.
The other end is connected to a box. The box is pulled to the right, stretching the spring. Static friction exists between the box and the table, so when the spring is stretched only by a small amount and the box is released, the box does not move..
Given a char variable called gender, write C++ statements to output "Male" if gender contains upper or lower case M, "Female" if it contains upper or lower case F, or "Invalid Gender" if it contains anything else. Use if / else if statements.
Describe how an inductor is practically consumed and what are the problems with practical inductors
Design an RC-Low Pass Filter with cutoff frequency at fc=0.5GHz and plot its frequency response and design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
Find an application note or data sheet that describes a piece of hardware or software that performs Manchester encoding and decoding. Describe the method used for signal encoding, decoding, and clock recovery.
A filter with a great deal of attenuation must be placed in an amplifier chain. Ignoring all considerations other than the desire to minimize noise figure, would it be preferable to put the filter before or after a low noise amplifier Why
determining whether the number divided evenly can be accomplished by determining if there is a remainder. Implement the program using a for loop for the calculations. Additional hint: a break in the loop can make the program simpler, though it is ..
