Task 2. Calculation of linear electric circuit of sinusoidal current

The general pointing over in relation to determination of variant, implementation and registration of the second task of domestic task is brought in pointing of the first task.

Pointing to the concrete task:

- in a table 3 the effective values of EMF are set;

- frequency of current of all sources equals to f = 400 Hz;

- one source of E_k operates in a circuit only, the index of "k" is
determined after a table 3;

- by conductivity of voltmeter to neglect.

Table of contents of task

For the given electric circuit of fig. 2 to execute the following:

- to define the effective values of currents in all branches and voltage
drops across circuit component by a comfortable method;

- to check up exactness of the executed calculations, taking
advantage of equation of active and reactive powers;

- in a comfortable scale to build the radial vector diagram of currents
and topographical vector diagram of circuit voltage;

- to define voltage, which will be shown by the voltmeter of the
electromagnetic system, connected with terminals in the points of M and N
set by a teacher;

to write down the instantaneous values of all currents and voltages;

- to formulate short conclusions on work.

A number of variant and data is to the calculations
