    Answer:

    3 ohm

    Explanation:

    Given :

    V=9V

    And according to given question same current is flowing in both resistance that means resistance will connected in series

    So,

    R= R+R=2R

    Now,

    Applying ohm’s law

    V=IR\\9=1.5*2R\\9=3R\\R=\frac{9}{3} \\R= 3ohm

    Therefore, answer is 3 ohm
