    Answer:

    you didn’t say if its a parallel or a series circuit

    Explanation:

    If it’s a series circuit

    V =IR

    v = 13 \times 3(4) \\ v = 13 \times 12\\ v = 156v

    However in parallel

    calculate the Rp which will be

    rp = \frac{1}{4} + \frac{1}{4} + \frac{1}{4} \\ rp = \frac{3}{4}

    so now you can say V=IR

    v = \frac{3}{4} \times 13 \\ v = 9.75v
