    Thumbs up

    Hi, Sarma

    V. Good idea ...

    If you use a series resistor AND a capacitor between resistor and ground ( say 100 to 470 µF ) you will have enough energy to power up the relay ... and the resistor will limit the quiescent current ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
