Introduction
Calculation Graphical Works (CGW) is an essential component in the study
“Electrical Engineering Theoretical Bases 1” (EETB1) course. Performing CGW
allows the student to apply theoretical principles in practical calculations, to gain
the skills of independent circuit analysis that ultimately contribute to the successful
mastering of the EETB1 course.
This brochure contains assignments and methodological guidelines for three
CGW on the main sections of the EETB1, which should be studied in 3-rd semester.
CGW в„–1 is devoted to calculation of a DC branched linear electric circuit by
using the basic circuit analysis methods.
CGW в„–2 and CGW в„–3 are devoted to calculation of the single-phase sinus-
oidal current linear electric circuits by using a complex method.
Variant of original data is determined by the first letter of the surname, last
and penultimate digit of the credit book number and by the year of enrollment (even
or odd).
Requirements:
- CGW should be included next sections: introduction, assignment, procedure
of calculation, results presentation, conclusion and list of references;
- choose the original assignment data according to your variant, assignments
text should be rewritten to the explanatory note completely unabridged;
- each stage of a CGW should be named, all tasks are performed on only one
side of a sheet (size A4);
- in an explanatory note to be presented not only calculation formulas and fi-
nal results, but also text with explanations, needed intermediate calculations, that
allow to understand and verify your actions;
- variant number, academic group, surname and initials of the student should
be written on the title page; a template of the title page represented on the next
page;
- it is necessary to write appropriate units for the parameters, having a partic-
ular of dimension;
- put a dot over complex parameters, that are a time function;
- underline a complex parameters, that are not time function, such as imped-
ance and admittance;
- do not change of names of the nodes, parameters, resistors, inductances, ca-
pacitances and of the arbitrarily taken current and voltage positive directions;
- plots of instantaneous values, phasor, topographic and circle diagrams to be
performed on the pasted sheets of graph or checkered paper, or by using computer
applications;
- it is necessary to sign coordinate axes name and the names of variable on
the graph, also choose a scale so that would be convenient to use a graph or dia-
gram;
- circuit diagrams in the explanatory note should be done in pencil using a
ruler, or by using computer applications.
