    Answer:

    2volts

    Explanation:

    Let us assume the resistor are in series

    Equivalent resistance = R + 2R + 3R

    Equivalent resistance = 6R

    Since different voltage flows through the resistors

    V = IR

    Given V = 12V

    I = 2A

    Assume R = 1ohms

    V = IR

    V = 2 * 1

    V = 2volts

    Hence the potential difference across the resister with resistance R is 2volts
