Question

1.19 Find I and the power absorbed by each element in the network of Fig. 1.30. 8A9v 6 Figure 1.30 For Prob. 1.19. 1.20 Find V, and the power absorbed by each element in the circuit of Fig. 1.31. 1.- 2A 28 V 12 V TIA 28 V 30 V + 6A1 Figure 1.31 For Prob. 1.20.

Answer 1

solution L:19 IL 2A B e + 3N P21 SA Otev 0 9 oC Apply KCL at the terminal B. 8=2 tI I= 8-2 INGA Poce en = Veltage x cuoient Power absorbed by current source of Amp. current is P = - 8X q = - 72 Watt Povesi aluated by elementi, qv valtge is acrae it P2 = 9x2 = 18 Walt Pauer abwasibed by element 2 is P₂= 3x6 = 18 watt Power absorbed by valtage POUCO source of voltage GV is G = 6x6 = 36 walt

I=2H 4 1.20 salution 281 Garop 06 Ⓡemot IBA Apply KVL in mesh o 30 - 12-Vo =0 [vo = 180] - Peaer = valtage & cwarent leesest abvealed by valtoge furce is P = 30X(-6) = -180 Watt Power abwasibed by element is B = 12x6 = 42 watt Valtage acell element 2 is Vo =18 Poguer absorbed by element 2 is P₂ = 18x3 = 34 Watt Iz = 54 Walt

Power absorbed by element 3 is Pq = 28x2 = 56 Walt Power absorbed by element 4 is r = 28x1 = 28 watt Valtage achou dependent valtage sauce w = 5X2= LOV 51. Poceed abrogibed by dependent valtage source Po= 10x (-3) = - 30 watt
