Questions and Answers

What does Kirchhoff's Voltage Law (KVL) state?

  • The voltage across any element is equal to the current flowing through it.
  • The total work performed in moving a test charge around a closed path is non-zero.
  • The sum of voltages across elements in a closed loop is non-zero.
  • The sum of voltages around every closed loop in the circuit must equal zero. (correct)

    • In KCL equations, which node is typically discarded to avoid redundancy?

  • The node at the top of the circuit
  • The node at the bottom of the circuit (correct)
  • The node with the lowest voltage
  • The node with the highest voltage

    • What is the purpose of adding or subtracting two KCL equations?

  • To double the number of variables
  • To simplify the circuit analysis (correct)
  • To introduce errors in calculations
  • To complicate the circuit analysis
