Explanation Given: The given figure is i a = − 1 A i c = 3 A i g = 5 A i h = 1 A Calculation: The closed networks are called the circuits. All the circuits are the interconnection of junctions. There are 2 kind of junctions, that is, A current junction − Node. A voltage junction − Loop. According to Kirchhoff's current law, the vector sum of all the currents coming in the node and going out of the node is zero. The circuit can be drawn as Apply KCL at node 1, i a + i c = i b -1A + 3A = i b i b = 2 A
