Understand the rules for connecting electrical measuring instruments to electric circuits for the measurement of voltage, current, and power. Definitions Branch Any portion of the circuit with two terminals connected to it is known as branch. A branch may consist of one or more circuit elements. The current will be same throughout the branch. Node/Super node A node in an electrical circuit is a point at which two or more elements are joined together. A super node is a closed surface enclosing part of a circuit. It may contain some sources and other nodes. 22 EE1002 Introduction to Circuits and Systems R1 Super node Branch R2 Node1 ia v1 Node2 Node3 Branch V1 Branch V2 R4 ie R3 Node4 Fig. Circuit showing Branch, Node and Super node Mesh and loop A mesh is a closed path in the circuit. A loop is also a closed path in the circuit. The difference between loop and mesh is that a loop may contain other meshes or loops inside it, where as a mesh cannot have any other mesh or loop inside it. In the figure, loop2 and loop3 are meshes,...
