    Sir please to solve the question.

    An ac relay has a pick up current of 4mA and requires a pick up voltage of 140v ac/50Hz. The winding resistance is 20Kohm.
    A capacitor must be connected in series in order to reach the pick up current at 100v ac/50Hz. Calculate the required capacitance.
