Yes, everything is good now. Thanks for help.

I don't remember how the problem was worded exactly, but I'm sure that the only information that were given to set up the plant (transfer function) was that there's a pole with ωn=0 rad/sec and another pole with ωn= 2 rad/sec. As for the system transfer function, it wasn't mentioned whether the...

Homework Statement How do we set up a second-order plant transmittance with the only information available are: One pole is at a position where the undamped natural frequency (ωn = 0 rad/sec), and the other pole is at a position where ωn = 2 rad/sec? The question asks to build that...

He doesn't give away a model answer sheet. This question came in the final exam, which is very easy overall, for a course that's titled Electrical Engineering Technologies. It covers a wide range of topics on electrical and electronics measurement systems, devices, components...

If I add a resistor in series with the load, I would still be asked to have a constant voltage around RL only, which wouldn't be achievable in this case because of the voltage drop on the added resistor. The questions explicitly asks to prove that the voltage on RL hasn't changed after...

The symbol is for a capacitor, but it's just a misprint from the instructor's side who also emphasized that it's a DC voltage source and the load is pure resistive. I actually didn't pay attention to the wording of the question during the exam, so I didn't figure out what's wrong with it until I...

Homework Statement I had the question above in an exam. Although it's very trivial to analyze, I'm wondering what's wrong with part (e) of the question. It could be that I don't understand the hidden meaning behind this question, but I see it as obvious as that the current through RL...

Yes, it did. I got the desired DC output, 4.3 V, of course not exactly, only with a difference in hundredth. On the zener, no, I don't know about how much of a problem it would be if it's used for regulation. Can you explain further on zener and about the problem of the series resistance?

@Runei Yes, my design was based on the 4 didoes configuration, smoothing capacitor and zener diode for shunt regulation. I used the famous 1N4007 diode for rectification, which breakdowns at a peak reverse voltage that exceeds 1000V according to its datasheet ("tinyurl.com/9264lrg" )...

Basics? If you mean the introductory circuit theory, or the advanced one which covers Laplace and Fourier, and in addition to the first Electronics course which covers diodes, BJT and MOSFET, then I have had all of those covered. Now, I'm going through digital design and an introductory course...

Is that how electronic manufacturers measure the current needed for an electronic device to operate? Let me assume the following scenario. I made a well-constructed electronic circuit and I want to power it using an AC-DC converter it so that it can operate. I have the following questions...

@sophiecentaur I want to take the opportunity and ask a relevant question. If I want to make an AC-DC converter of an output DC voltage of 6V, how can I figure out the maximum current that the circuit can supply? why is there a difference in current of the two adapters, one with 0.7A and...

Frustration always gets me when I see myself not doing any major progress, especially when you study a field that's so diverse and interconnected, electrical engineering in my case. I get rid of frustration by two methods. The first one, work on a challenging pencil and paper problem, or on...

I won't give a direct answer to this, but here's a brief study on this subject which will answer your question, and in addition to this, it gives more insight into this nonsense...

There are countries in which high school students are taught that biological diversity exists because of god's will and wisdom. They admit that adaptation occurs but only because god created the structures and characteristics that enable different organisms to adapt to their respective...
