In an analysis nodal employs LCK to determinethe voltages of the nodes,which define regarding a common point or node of reference in the circuit under an analysis. With frequency this node is one to the that this connected the main number ofbranches and to the that comúnmente designates him earth due to the fact that it says that this to a potential of earth cero and some times represents the line of earth in a practical circuit.
Inthis type of analysis, the variables in the circuit choose like the voltages of the nodes.Said variable select like positive regarding the node of reference, of such form that if any of the voltages ofthe nodes is negative regarding the node of reference, the analysis indicated it.
Since the existence of a voltage define between two nodes, to the node of reference has to him associate in a...
