Soho: Here vir 12 V = 5 v V 227 3 2 16v - Applying junction rule at Point B 13 - Il + Iz ---(1) Applying Loop rule in loop EBAFE - V - V2 = 2 Iz + 412 > 12-5 = 2 (II+I2 + 4I2 2 211 + 6 12 2 7 ---- (0) Applying Loop rule in loop BED CB V3 - 51 - 412 --- D) → 511-412 2 16 - -- (in) (11)X 2 - (11) x 15 we get 101 - 81 32 1q 1 & 30 I2 235 - 38 12 2-3 IZ 3/38 A := 0.07898 A09 From egn. (1). we get 21 + 673 77 = 211 2 7 - 18 = 266-18 = 228 - 3263 A 7I, - 13. A. Focom egreco) 13 2 11+I22 39 +32 27 A. 3.342 A. Current Through 22 resistor 3.342 A. Current through ar Meristor 3.263 A f or resistor 0.0789 A To solve this problem we use ohm's law, junction rule, Loop rute. . 240
