Consider the following two statements (A)
Kirchhoff's junction law follows from the conservation of charge. (B) Kirchhoff's loop law follows from the conservation of energy. Which of the following is correct?Solution
Kirchhoff's junction law states that the amount of charge entering a junction must equal the amount of charge leaving it. This is because charges are always conserved. Kirchhoff's loop law states that the net potential drop in a loop is zero. This means that the total energy gained per unit charge must equal the amount of energy lost per unit charge.
