Questions and Answers

What is Kirchhoff's voltage law (KVL) stating?

  • The electric potential energy lost at each load is directly proportional to the amount of charges passing through.
  • The number of charges that will take each possible path is governed by the electric potential difference.
  • The sum of the increases in electric potential is equal to the sum of the decreases in electric potential around any complete path through an electric circuit. (correct)
  • The electric potential difference is directly proportional to the electric current in circuits.

    • What does Kirchhoff's current law (KCL) describe?

  • The number of charges that will take each possible path is governed by the electric potential difference.
  • The electric potential difference is directly proportional to the electric current in circuits.
  • The total current entering a junction is equal to the total current leaving the junction in an electric circuit. (correct)
  • The sum of the increases in electric potential is equal to the sum of the decreases in electric potential around any complete path through an electric circuit.

    Study Notes

    Kirchhoff's Laws

    • Kirchhoff's voltage law (KVL) states that the sum of voltage changes around any closed loop in a circuit is zero.
    • Kirchhoff's current law (KCL) describes that the sum of currents entering a node or junction in an electrical circuit is equal to the sum of currents leaving the node.

    Kirchhoff's Contributions

    • In 1845, German physicist Gustav Kirchhoff described Kirchhoff's laws, which are fundamental principles in electrical engineering.

    Electric Circuit Analysis

    • The voltage of the source governs the amount of electric potential energy charges will lose at each load in an electric circuit.
    • The resistance in each path governs the number of charges that will take each possible path in an electric circuit.
