How do I know which KCL & KVL equations are independent? I mean I can make the equations but that little detail is kinda tricky to me

    For KVL, the number of independent equations = number of small loops that can be formed. By small loop, I mean a loop that does not contain another loop within it. Number of KCL equations = number of nodes minus 1. If you have 4 nodes, you can use any 3 nodes to create equations, but often one will stick out as a good reference point, making the equations a little simpler, and not used. Hope that helps.

    for KVL first of all identify no. of mesh..then assume individual current for all mesh.. now for all individual mesh write eqn sum of all drop in a mesh=sum of all applied sources..

    can you elaborate sharadtripathi? thaks Tweedle good answer I was looking now for a math way of knowing the exact number of independent equations you reasoning seems right thank you so much
