Problem # 1. Simple D C circuitInitial data:NoU, VR1,R2,R3,R4,R5,R6,I1,AI2,AI4,AI5,AI6,ARtotal,Uab, V20160441030121210,56,563.933,283,2815,25118Total resistance in the circuit Rtotal , potential difference nudes a and b Uab, and current values in all branchesOhmas Law for the all currents. :;;;;;.All I an Uab values writes in table.3. Balance between power supplies and consumed.;;.Problem # 2 Complex D C circuitFor given D.C. circuit:1. Find current values in all circuit branches;2. check the balance between power supplies by the sources and consumed in resistors.Initial data:NoR1,R2,R3,R4,R5,R6,E1,VE2,VE3,VE4,VE5,VE6,V8251113150---80(-90)-I1,AI2,AI3,AI4,AI5,AI6,A1. Current values in all circuit branches:I Kirchhoff’s LawN1 : I3 - I6 - I1 = 0 ;N2 : I1 – I4 - I2 = 0 ;N3 : I2 – I5 - I3 = 0 .II Kirchhoff’s LawL1 : - I6 – I1 R1 + I4 R4 = E4 ;L2 : - I5 R5 - I4 R4 + I2 R2= E5 –E4;N3 : I3 R3 + I6 R6 – I5 R5 = -E5 . 2. Balance between power supplied by the sources and power consumed in resistors.;833W = 833WProblem#4. Capasitors connections, and the Kirchhoff’s Law.1. For the circuit determine the equivalent capacitance Ceq at terminals a - b ; capacitors in sequence mode, ;capacitors in parallel mode, ;2. For the circuit determine currents I1 and I23. For the circuit determine voltages Vx, Vy, Vz,
