please show every step. thanks in advance and I will upvote if clear and explained

4.Using Kirchhoff's laws find the values of the currents 11, 12, and 13, in the following circuit: 40.6 9v 20.12 12V 121 1

Answer 1

Given ; lon II Mon F I3 2 av 2022 12V turg Iz L2 I3 I From krichhoff's junction Law : at point B I 2 I + Iz From kirchhoff's voltage Cloop) law Iz In Loop L: ava 10xI, + 20 (I, +13) E I = I, I, ..) = 9 = 30 I, + 20 I3 In Loop h: 12v zoth & I) 12 = 20 I, + 20 Iz 2015 20 I, & By solving (1) & (2) 30 I, + 20 I3 I = -3 -0.3 I = I t I = 0.6A = I. I= - no 0.q A IE = -0.3 A , I = 0.6A Iz = = 0.9A
