  • question_answer
    The power is transmitted from a power house on high voltage ac because                                           [CPMT 1984, 85]

    A)            Electric current travels faster at higher volts

    B)            It is more economical due to less power wastage

    C)            It is difficult to generate power at low voltage

    D)            Chances of stealing transmission lines are minimized

    Correct Answer: B

    Solution :

               Power loss \[\propto \frac{1}{{{(Voltage)}^{2}}}\]
