HI evrybdy---new here---havin ma papers so plz anybdy tell me abt mesh analysis and branch current method plzzzzzz

In the AAC text, it is stated, but rather lost in the detail, that the currents involved in MESH analysis are imaginary. That is they are not the actual currents flowing, although obviously we can derive these actual currents from our imaginary ones. The reason for this is that it can make the arithmetic easier, depending upon what we wish to calculate. On the other hand the branch currents (also better called the node currents) work directly on the actual currents flowing.
