In modified nodal analysis, an ideal voltage source connected between two non-reference nodes is commonly handled by introducing?

  • AAn additional source-current unknown and a voltage constraint equation
  • BAn open circuit in every case
  • CA short circuit in every case
  • DOnly a mesh-current equation with no node voltages
Report an error
Correct Answer: A. An additional source-current unknown and a voltage constraint equation
Explanation: Modified nodal analysis augments the node-voltage equations with an unknown current through the voltage source and an equation enforcing the source voltage.
