課程概述

This course explains how to analyze circuits that have direct current (DC) current or voltage sources. A DC source is one that is constant. Circuits with resistors, capacitors, and inductors are covered, both analytically and experimentally. Some practical applications in sensors are demonstrated....

The course is very helpful to us to understand the DC circit analysis a lot.Thank you to the team.As a faculty,I know the concepts well.So directly went to the quiz part.

The course is very good for beginners and lab experiments related to sensors are good .Explanation of concepts with real time applications is a good asset of this course

This course closely mirrors what I've seen in the first chapters of circuit analysis textbooks. There are a good amount of examples and practice problems with worked solutions and the lectures are clear and concise. But, there are some quizzes that only accept answers rounded in a certain way (without telling you), or answers that the auto-grader marks as wrong incorrectly. This leads to many hours spent scouring the forums for people who have had similar issues, or trying different solutions until something works. There are also quizzes that are either significantly more difficult than the example problems in the week's lesson, and quizzes that are much easier than the content covered. The community is active for the first couple of weeks of lessons, but then tapers off. Also, it doesn't seem like the faculty support the course actively. This would definitely be a five-star course if the auto-grading issues were fixed and it was a bit better supported.

There was good content in the course. It definitely gave me the background information that I needed to make a career change into electrical engineer. The course instructors themselves were also excellent. However, there were several issues with the course that prevent me from rating it more highly. In no particular order, practice and quiz problems often cover material not presented in lectures (e.g. Op Amps--in fact, whole different sections of the course are alluded to in some lectures that don't seem to appear anywhere), many times correct answers are rejected by the grader (or there is no correct answer at all, as happened in the Module 6 Quiz), and sometimes entire problem sets are repeated in different lessons (half of the questions for the Module 7 Quiz come directly from the Module 5 and Module 6 Quizzes).

The lectures are very good, but the practice problems and quiz grading keys have a large number of errors that were never corrected. There don't appear to be any moderators.

If something's marked wrong, go to the discussion board and see what the other students who appear to be understanding the material say. Sometimes other students have discovered the quiz asked for voltage, but accepts current as right, sometimes it asks for answers rounded to three decimals but only accepts the answer rounded to 2, other times the answer is clear, but nobody's managed to figure out what the grader wanted (particularity on the quizzes for the final two weeks. Overall, good course to audit, but Coursera shouldn't be charging for quizzes until they are fixed.

You can learn a lot from this course, but it isn't worth paying for the circuit. This course isn't maintained and there are a lot and I really mean A LOT of mistakes in the quizes, practice exercises and slides. Also sometimes the material quized doesn't correspond with the material discussed in the lecture. The last two modules aren't really DC Analysis anymore. They are better put in their AC analysis course as they cover Transient responses. In conclusion, you can learn a lot from this course, but be prepared to dive into the discussion form to find out that this course has a lot of annoying mistakes.

The course is a great way to review the basic circuit analysis. The content is good enough to solve for the dc parameters for any circuit irrespective of how complex it is. My main issue has been with number of errors in the course materials which can be really frustrating at times, including ones at the week end quizzes. Also instructors are not at all responsive, there is no reply whatsoever for any raised issue and looking at forums, i know this has been going for a long time now.

Not very good quality course. I do not know what the "Extra Problems" are put there for. They look not related to the other lesson videos. No one explains what do they mean.

There is also some mistake in the practice items. It has been there for long time and it is never corrected.

Not a good learning experience. Doctor Ferri always says she is looking forward to see us in forums. But even the basic stupid wrong answers could not be corrected. Very disappointing.

The course overall was pretty frustrating. Quite a few instances of the answer key being wrong and the lecture videos not adequately preparing you for the practice questions. I was still able to pass the course and learned a lot, but I already had a good amount of background in circuits and needed to find other references to progress through the course. The course could be significantly approved if these relatively simple issues were addressed.

It's a good course but a huge part of it is a complete mess. Wrong exercises, no one answer your messages (and when I say no one, I mean the course managers) and sometimes the exercises have nothing to do with the specific subject. However the profesors did a great job and I have to thank them for the precious invested time doing this. The lessons are good and straight to the point.

The professors due a superb job of explaining all the theory and how to solve problems. However, too many to count, the answers to the quizzes are incorrect and any feedback sent in is just ignored. For a University of this caliber to not monitor its website nor correct wrong quiz answers ruined what could have been a great learning experience.

The course itself is good, but there are A LOT of mistakes in the quizzes and in the video slides. Unfortunately, it seems that the stuff just does not care at all about it, because there is absolutely 0 feedback from them in the discussion forums, and the mistakes pointed out by dozen of students never get corrected.

2020年5月7日

The course was not so bad, but the one thing that was a disaster is that the extra problems were not always possible because it systematically required stuff from the next week and it was, therefore, difficult to do the mini-quizzes that followed them. Also, there were some problems that had an incorrect solution.

This course is really good for introduction to DC Analysis, but you will be on your own in terms of asking for help when working on the problems and quizzes. You can get extra help online but I would recommend this course for first or second year engineering students and if you want a refresher on DC Analysis.
