    The 12V source sees 680||820 + 960

    680*820/(680+820) +960 = 1332Ω <<<< Req <<<<< A)

    The current leaving the 12V source = 12/1332 = 9mA

    960*9mA = 8.65V

    Voltage across 820 = 12 - 8.65 = 3.35V <<<<< B)

    Voltage across 960 =  9e-3*960 = 8.65V <<<<< C)

    Voltage across 680 = 12 -8.65 = 3.35V <<<<< D)

    equivalent resistance as seen by the battery?

    R1 = 960 + 820•680/(820+680)

    I1 = 12/R1

    c) V1  = I1(960)

    b,d) V2  = 12 – V1
