Description: Circuit Analysis Techniques
We learned that KVLs, KCLs, and i-v characteristics equations results in a set of linear
equations for the circuit variables (typically 2E equations in 2E circuit variables where E is
number of elements).W e learned that we can use i-v characteristics equations when we are
marking the circuit variables and reduce the number of equation to be solved to E equations
in E unknowns (which is the same as number of KCLs plus KVLs).In this section, we
learn two methods, node-voltage and mesh-current, which reduce the number of equations
to either number of KCLs or number of KVLs.These are node-voltage and mesh-current
methods.T hey also form the basis to deduce certain properties of linear circuits.
