Answer 1

V=98 8 RI with =2.60 e By Applying junction rule Iz = It In - R2 T Iz By Applying loop rule, 7 V3=64 g- (22+ 2.60) I + 18 I 2 = 0 – 24.6I, + 18 12 =-9 - ② 6- 2060 I3 - 18 I2 = 0 from 0 - 2.60(1;+ 12)-18 I2 =-6 2.60 11 + 20. 6 I2=6 - ③ by solving ② & 3 Il = 0.53A Iz = 0. 22A Is, Iz = 10.53,0.22 A B I to the left, Iz to the left (see drawing bugure (above))
