Name: x

Group: x

Variant: 2

Date: 

Purpose of the work: Learn to apply main electrical laws to passive circuits and simplify schematics.

Process of work: a common process is getting acquainted with the schematics and making the calculations. Specific steps that were done in every assignment will be described in each of them.

L ab task assignment No. 1

2. а) There are 9 branches in Fig. 1 The branches are: V1, R1, R2, R3, R4, R5, R6, R7, R8

b) There are 5 nodes (according to the rule, that the node is a connection between of 3 elements) on the Fig. 1 Nodes are V1-R1-R5, R1-R3-R4, R3-R4-R6, R6-R8-V1, R8-R7-R5)

c) Fig. 1 has 6 (V1-R1-R3-R4-R6-V1, V1-R5-R8-V1, R1-R4-R6-R8-R7-R2-R1, R2-R7-R5-R2, R1-R3-R4-R6-R8-R5-R1, V1-R8-R7-R2-R1-V1) contours.

3. Simplification process:

All resistors have the same value of 2kΩ.

1^st step: R3 and R4 are parallel ones and can be displayed as 1 resistor R34, R34 will obtain next value: , resistors R5 and R7 are in the parallel connection as well so they will be located as 1 resistor R57, R57 = . R2 would not pass the current through itself, as there is a wire with 0 resistance (in ideal conditions), the current would flow through the wire, so it is possible not to count R2 at all.

The result of 1 step will be shown in Fig. 2.

Fig. 2. 1^st step

2^nd step: R1, R34, R6 are serial, they will be replaced with R1346 = 2 + 1+ 2 = 5 kΩ, R57 and R8 are serial, they can be displayed as one resistor R578 = 1 + 2 = 3 kΩ. The simplified version of the circuit at the 2^nd step will be represented in Fig. 3
