E2 = 21 V
E3 = 22.5 V
R1 = 6 Ohm
R2 = 12 Ohm
R3 = 9 Ohm
R4 = 15 Ohm
R5 = 19.5 Ohm
R6 = 15 Ohm
EK2 = R2IK2 = 12 ∙ 2 = 24 V
EK3 = R3IK3 = 9 ∙ 1 = 9 V
 
It is necessary to perform the following actions:
1. To compose on the basis of Kirchhoff´s laws a system of equations for the calculation of currents in all branches of the circuit
2. Determine the currents in all branches of the circuit by the method of contour currents
3. Balance the power by calculating the individual total power of loads (resistances)
4. The results of calculating the currents, carried out by three methods, are reduced to a table and compared with each other
5. Identify the functional dependence I6 = f (R6), if the remaining parameters of the circuit remain unchanged. The analysis is carried out using the equivalent generator method (active two-terminal network)
