Question

Please post a detailed solution. I'm stuck and I can't find my mistake.

11 2 R₂ 12 Loop 3 Loop 1 R2 Loop 2 +lului V2 Consider a circuit as shown in figure. Write down the convention for sign that's used to apply Kirchhoff's loop rule. Finally, after properly labeling junctions, find the current equation at junctions and find the loop equation of the 3 loops shown in fig- ure. R5 +16 12 R1 R4 14 15

Answer 1

B Answer:- Rz T I 2 ₂ (loop-2 (Loops (loop-3) V Ty C politive Ig Rg Ry sign convention for KCL, For KCL, incoming currents are taken as and outgoing currents are taken as negative at a node. For KvL, while traversing loop/mesh, there is a potential rise moving from negative to positive terminal of a battery moring against the direction of current through a resistor.
