A 35 kHz sinusoidal voltage has zero phase angle and amaximum amplitude of 10 mV. When this voltage is applied across theterminals of a capacitor, the resulting steady-state current has amaximum amplitude of 644.73 microAmps.What is the impedance of the capacitor?
Male frogs give calls that attract female frogs to approach and mate. Researchers examined mating calls of closely related tree frogs in South America. If reinforcement of postzygotic isolation is occurring
The transformer is to be used on a 50 Hz system, with the restriction that it maintain the same maximum core flux and the same total losses. Determine (a) the new voltage rating; (b)the new kVA rating.
You are the operator of a 15,000 V 60 Hz electrical substation. When you get to work one day you see that the station is delivering 6.0 MW of power with a power factor cosf=0.9. What is rms current.
Design your concept of a device and describe its operation in terms of the topics in the course (solid states course). For example, maybe you can make a new type of solar cell based on semiconducting liquids
Discuss these possible reasons, indicating which are the most important: The field is so young; such different needs; there are so many types of systems; and people with widely different backgrounds are developing.
The excitation branch impedances are given referred to the high-voltage side of the transformer. a) Find the equivalent circuit of this transformer referred to the high-voltage side.
Dispense requested amount using least number of bills, Write a C program for an automatic teller machine that dispenses money. The user should enter the amount desired (a multiple of 10 dollars)
Does anyone understand this solution. It looks like they arecompetely ignoring the 30V source. And then when you remove thesources to find Rth, the 40ohm and 10ohm resistors look to be in series to me
Use a 5nF capacitor to design a series RLC bandpass filter in series. the center frequency of the filter is 8kHz, and the quality factor is 2. perform the analysis in Pspice and graph the transfer function on the y axis vs.
a) Using a table of the Gaussian distribution, determine an exact value for P[|X-n|>=2.5sigma] b) What is the upper bound on P[|X-n|>=2.5signma] given by the Chebyshev inequality
A continuos-time system is given as a differential equation: y''(t)+2y'(t)+3y(t)=x'(t)+x(t-2) a. Compute the Transfer function H(s) of the system. b. Compute the Impulse Response h(t). c. Compute the Step Response g(t).
Assume that a transmitter on Earth must communicate with a spacecraft on the Moon. Parameters are: Earth-based atenna gain=40dB Lunar receiving atenna gain=20dB Distance=386,000 Km Frequency= 3GHz Minimum lunar signal level = 100fW
