In electric circuits analysis, nodal analysis, node-voltage analysis, or the branch current method is a method of determining the voltage (potential difference) between "nodes" (points where elements or branches connect) in an electrical circuit in terms of the branch currents.
Correspondingly, what is a Supermesh and supernode?
Supernodes are used to do nodal analysis on circuits containing voltage sources. Supermeshes are used to do mesh analysis on circuits containing current sources. You make a supermesh for each pair of meshes where a current source lies on a branch shared by two meshes.
What is the meaning of reference node?
The voltage drop from a node to the reference node (ground) is called the node voltage. To keep definition simple, node voltages are usually defined with positive polarities. Let's find label node voltages in the following circuit: The circuit has 5 nodes: Two of the nodes have 4 elements connected to them.
What is Supermesh analysis?
Supermesh or Supermesh Analysis is a better technique instead of using Mesh analysis to analysis such a complex electric circuit or network, where two meshes have a current source as a common element.
