Question

If there is a common branch with a voltage source alone between two meshes, then the combination is called:

• A. Super node
• B. Super mesh
• C. Single mesh
• D. Single node

Hint:

Voltage source between two meshes → form a super mesh by excluding the source and applying KVL to the outer loop.

Answer 1

The Correct Option is B

In circuit theory, when analyzing mesh currents in a circuit using the mesh analysis method, encountering a scenario with a voltage source shared between two meshes requires special handling because the traditional KVL cannot be directly applied around the voltage source. This situation leads to the formation of a super mesh. The super mesh combines the two meshes by essentially ignoring the current through the voltage source but accounting for its influence in the super mesh equation. Therefore, when there is a common branch with a voltage source alone between two meshes, this creates:
