Really thanks Sir good explanation, in this i have one doubt, in this video while creating matrix we consider number of loops as per KVL, whereas in Nodal analysis we consider number of nodes as per KCL, my doubt is in both the cases the number of loops & nodes where 3, but in Mesh analysis you have taken the count as it is, whereas in nodal analysis you have taken the value 2 by subtracting 1, why is this difference why are we not taking in both the cases 3, even though the node & loop count is 3 ?.. Kindly Explain
In nodal analysis Say for example 3 nodes, Va,Vb,Vc Where Va, Vb, are unknown we need to find out, But Vc is ground so Vc=0 Hence only value of 2 node Va, Vb need to be findout, so for 3 node 2 unknown, therefore (3-1=2) 2x1 Voltage matrix, 2×2 1/R matrix, 2x1 I(current )matrix In general for N node (N-1)x1 Voltage matrix, (N-1)×(N-1) 1/R matrix, (N-1)x1 I(current )matrix
20 v to -20 for v3 according to i3 direction but while explaining Maxwell current in part( 41 ) you have said to take + sign in accordance to I direction for eqn. If Maxwell & mesh current analysis r same why it's different .
