Question

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

Answer 1

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.

Answer 2

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..

Answer 3

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
