The EI1120 homepage has a link to the KTH Schedule with the dates, times and rooms for course events such as lectures and tutorials. The homepage itself presents all the course-material, in the sequence in which it is expected to be used for lectures, tutorials, exercises, homeworks, labs and tests.
Support via Funka:
if you have a disability, you may receive support from
Funka.
Support from teachers: Funka does not automatically inform the teacher about your needs;
so we recommend you inform the teacher about any need you have
that cannot be met by Funka.
The Student Office, STEX, is the proper contact
for all questions about registrations to the courses and exams:
e.g. late registration, web-based registration not working, re-registration,
problems with viewing marked exams, etc.
See the STEX webpage
for contact details,
or visit the office in the entrance to Osquldasväg 10.
These sorts of administrative questions should not initially come to
the course teachers -- we do not even have access to some features of the
administrative systems, and the rules and details are complex beyond our
comprehension.
You should register for the course as soon as you start it. For new registrations, use Mina Sidor. If you're repeating the course you should re-register, by emailing STEX or visiting STEX (see above).
Note the new KTH exam rules in 2017: 
KTH tentaregler; if you are not registered, you need to wait for a chance to enter, and to prove your course registration on paper ... better just to ensure you register for exams (tentor), re-exams (omtentor), and mini-exams (kontrollskrivningar).
Registration can be made on Mina Sidor. See the above link for the times when registration is open.
When multiple rooms are booked for exams/KS, STEX will email to each exam-registered student (between 1 and 3 days before the event) to say which room to go to. Do check your (KTH) mail, including the junk, if you find you haven't had this notice a day before the exam.
See the Books page for more information. There is no book that you are supposed to use as the main course book. The files provided on this website are the course literature, along with questions and solutions from homeworks and past exams. An old KTH compendium is suggested as a source of further practice questions and correct Swedish terminology.
See study habits ... please!
If you're looking for a Syllabus (list of "learning outcomes", purpose of course, etc), it is probably most useful to look at the content of the notes, homeworks and past exams of the last two years. These give a detailed view of the included subjects and our emphasis, and of the typical style of problems that we solve. If you prefer formality, you can try the official course-plan: however, in view of the small space this inevitably cannot provide much information about the style and level (note also that we don't do much "mesh analysis" now).
The course is about analysis of linear circuits.
The main aim is to get competent at taking a circuit diagram and finding what values certain variables such as voltages, currents and powers would have. We will also sometimes look at the backward question of what parameters, such as sources and resistors, should be chosen in order to make a variable have a specified value.
We would like students to develop abilities in two rather different approaches to circuit analysis. One is the "intuitive sense", of being able to estimate some of the behaviour of a circuit from just looking at a circuit diagram. The other is to use systematic methods to translate a circuit diagram into a set of equations that allow a variable or parameter to be determined. Both of these are useful for real situations, and they are often used together. In practical use of circuit analysis, the former skill is important for making estimates and starting in the right direction with a design. The latter skill is important for dealing with later stages of analysis where more detail is needed, such as solutions of complicated circuits where we have to program computers to generate and solve the equations. The latter seems generally easier to train, particularly if the equations are to be solved by computer. In view of the large number of methods and concepts that we need to introduce in this course, and the opportunity of developing more "feeling" for circuits during practical applications in later courses, the course assessment is designed without rigid demands about demonstrating skills of estimation and conceptual thinking; however, some minor parts of exam questions can benefit from these skills.
A circuit diagram represents an idealised model: for example, a voltage source is assumed to give an exact voltage regardless of the current through it. The diagrams are thus directly related to equations. Idealised circuit analysis is basically a mathematical puzzle, with a special sort of representation! A large part of practically applied circuit analysis consists in choosing a suitable model (diagram) for an actual circuit, then solving the diagram (the straightforward part!), then analysing what the results means the context of the actual circuit. This can be surprisingly difficult; one has to decide what phenomena can safely be neglected. In this course we almost entirely omit the parts other than solving the diagrams. The other parts could be very educational, but we do not have time to deviate far from our quite idealised content. In our limited time, we want to get good core skills at solving the diagrams. Later courses will build on these skills, and apply them to the more practical applications in power, communications, control, etc.
Students taking this course should also use it as an opportunity to improve their general skills at checking the reasonableness of answers by methods such as extreme cases ("suppose we set R to zero, ...") and dimensional analysis. These skills are only required to a small extent in the course's assessment, but some sort of checking should ideally be used for all results; some credit is given for correctly identifying a wrong solution as being wrong. Checking is important in later studies and work, as well as in homeworks and exams in the course.
The course's subjects are divided into three Sections, which are studied in this sequence:
The exam has three Sections: A, B, and C, corresponding to the above list.
Partial completion of a Ladokmoment in a previous year is ignored: if you haven't passed it you need to fulfil the entire requirement during this new study period in order to pass it. However, any Ladokmoment that is already completed (registered as a pass) is kept (it's a basic rule that given grades can't be reduced).
To pass PRO1: Homework.
Some exam bonus points are given, in proportion to the number of approved homeworks that were submitted before their deadlines. This bonus is added to the total exam score before setting the grade. The bonus is directly proportional to the number of approved homeworks. At the most (for 12 in-time approved homeworks) the bonus is 4% of the exam points: this is nearly half a grade-boundary, and thus has a good chance of making a significant difference.
The exact calculation of exam grades can be seen at the top of last year's exam, 2016-03_EM_tenta.pdf. The bonus can thus affect even the pass/fail decision, but it cannot help if you get below the minimum for a particular section of the exam (40% for A and B, 30% for C); it only helps to change the total score, for which 50% is the pass level.
To pass PRO2: Lab tasks.
To pass TEN1: Written Examination (optionally including Kontrollskrivningar)
Permitted material at exam or KS (hjälpmedel).
For VT18 we do as in VT17: it's still 1 A4 paper at KS1, but then it's
permitted to have 2 at KS2, and 3 at the final exam or re-exam. That's so that
you can each time add one piece of paper with notes on the topics that were
studied since the last test, re-using the notes from previous sections of
the course.
The course teachers do not require these papers to be submitted with the exam,
but with the new KTH exam rules there's a risk that you will get asked
to leave all extra papers. Keep a copy, if you want to re-use your notes.
If you are re-registering from a previous year and have
not already passed PRO1 or PRO2, then you should do the homeworks
and labs (same conditions as the new students). If lab times are
a great trouble due to a job or other course, we may consider
alternative work.
