    Kirchhoffs law of junction, \[\sum{I=0,}\] is based  on :

    A) conservation of energy

    B) conservation of charge

    C) conservation of energy as well as charge

    D) conservation of momentum

    Correct Answer: B

    Solution :

    The junction rule\[\Sigma I=0\]is based on conservation of electric charge. No charge can accumulate at a junction, so the total charge entering the junction per unit time must equal to charge leaving per unit time.
