    In the circuit shown here, the voltage across Land C are respectively300 V and 400 V. The voltage E of the ac source is:                                                      [JEE ONLINE 09-04-2013] 

    A)             400 Volt

    B) 500 Volt

    C)             100      Volt

    D) 700 Volt

    Correct Answer: C

    Solution :

    [c] Since, reactance’s produced by inductor and capacitor in opposite direction. So, voltage in these elements are distributed at \[180{}^\circ \] i.e., out of phase.
    Net voltage = 400V - 300V = 100 V
