The three resistors 6, 6, 6 are parallel, and parallel to the resistance 1, so the external resistance is $\frac{2}{3}$ , with the internal resistance we get $\frac{5}{3}$ as the equivalent resistance of the whole circuit. I = $\frac{12}{5/3}$ = 7.2A V1 = V2 = 12 - 7.2 * 1 = 4.8V OR V1 = V2 = IR = 7.2 * $\frac{2}{3}$ = 4.8V.
