A supernode is formed in nodal analysis when an ideal voltage source is connected between?

  • ATwo non-reference nodes
  • BA node and a resistor only
  • CTwo current sources in series
  • DTwo reference nodes only
Report an error
Correct Answer: A. Two non-reference nodes
Explanation: A voltage source between two unknown-voltage nodes prevents direct branch-current expression by conductance, so the two nodes are treated together as a supernode.
Reference: Standard network theory: supernode
