Questions and Answers

What does Thévenin's theorem state?

  • Any linear electrical network can be replaced by a single ideal voltage source
  • Any linear electrical network can be replaced by an equivalent combination of a voltage source and a resistance
  • Any electrical network can be replaced by a combination of a current source and a resistance
  • Any electrical network containing only voltage sources, current sources, and resistances can be replaced by a voltage source Vth in series with a resistance Rth (correct)
  • What does the equivalent resistance Rth represent in Thévenin's theorem?

  • Resistance when all ideal voltage sources are replaced by a short circuit
  • Resistance when voltage sources are connected in parallel
  • Resistance when all ideal current sources are replaced by an open circuit (correct)
  • Resistance when current sources are connected in series
  • What is the equivalent voltage Vth in Thévenin's theorem?

  • Voltage when terminals A and B are short-circuited
  • Voltage when all resistances are replaced by short circuits
  • Voltage when terminals A and B are open circuited (correct)
  • Voltage when all current sources are replaced by open circuits
  • What is the current flowing from A to B when terminals A and B are connected in Thévenin's theorem?
