Hi, I am taking a Power Devices and Systems course and I am looking for a good textbook. The type of circuits/machines we are covering are: Power circuits; transformers; magnetic circuits; three phase connections; single phase motors; polyphase machines; synchronous generators and motors...

Homework Statement Design a DC cct having a 15V battery to provide the following node voltages: +10V, +5V, and -5V with respect to a circuit ground node. Select your resistors such that the max power demand on the battery does not exceed 1mA. The Attempt at a Solution I made a cct with 4...

Homework Statement Calculate the X, Y, and magnitude force between the two charges. Compare to the computer simulation results. Homework Equations Do not forget that this is a 2-D problem. Use the 2-D Coulomb’s law for line charges. The Attempt at a Solution Basically we used a...

Ohhhh...makes sense. Thanks a lot!

Homework Statement Prove the divergence of the harmonic series by contridiction Homework Equations Attached file The Attempt at a Solution I understand what they are doing in the first two lines, however, the lines after assuming the series converges with sum S, confuses me. They...

Homework Statement Using your results, calculate the 3dB frequency of the RC filter. The Attempt at a Solution Basically in our lab, we made a simple series RC low pass filter. We put in a 16V peak to peak signal at varying frequencies below, and measured the output voltage at the...

Im currently in 2nd year Elec Eng. We do have a course text: Engineering Electromagnetics by Hayt and Buck. I have yet to purchase yet as we do have a copy available on reserve in the library. The only other experience I have with electromagnetism would be First Year Physics. At this...

Hey, It seems as though there are many books on electromagnetism out there, but most that I look at have mixed reviews. Before spending money on a book, would you happen to have any reccomendations on a solid introductory textbook on electromagnetics? Thanks

great thanks a lot!

Homework Statement Our prof talked about arc length as a parameter today and I understand how to do problems associated with it, however I do not fully understand why we do it. Homework Equations In our text, the only relevant reading says: "A curve in the plane or in space can be...

Homework Statement To find the voltage-current relationship of a capcitor, integrate both sides of i = C(dv/dt) The Attempt at a Solution In the book they say, v = (1/C)(The Integral from -tve infitity to t) of i dt. or v = (1/C)(The Integral from tnot to t) of i dt + v(tnot)...

Hey, I started off programming in high school with Turing. I continued with that until Grade 10 and in Grades 11/12, I learned Visual Basic. In year 1 of university, I learned C, and now in Year 2, we are being taught Java. My problem is Java seems very foriegn to me. No matter how hard I...

Can anyone reccomend me a good book and introductory electrical engineering circuit analysis? I currently have Basic Engineering Circuit Analysis by Irwin/Nelms, but am not too fond of it. Thanks

Hey, For the attached question, the only part I do not understand is why the Thevenin Resistance is equal to R3. I thought it would be (R1 || R2) + R3 Can somebody please explain this? cheers!

ahhh I got to pay more attention...Thanks!
