Unformatted text preview: equations thatmust be manipulated.Thcy also require the analyst to be quite systematic in terms oforganizing and wdling these equations.It is natural to ask,lhen, "When is the node-voltage method preferred to the mesh-current melhod and vice versa?" As you might suspect. there is no clear-cut answer.Asking a number of questions, however, may help you identify the more efficient method belbre plunging into the solution process: . Does one of the melhods result in fewer simultaneous equations . Does the circuil contain supernodes? If so, using the node-voltage method will permil you to reduce the number of equalions to i 0 A...
