    \[(2ohm/3ohm)*I\] for v1 and for v2 its half, but over two volts the zener cuts dovn the voltage to 2V

    Q3: p1 : zener voltage sholud be less than the given current so vo=2V which is zener voltage Q3: P2 : I1=( 0.66 * I ) . . . also find I2 = (0.33 * I) .. . Vo= I2 Q3: P3 : (a) I1=( 0.66 * I ) . . . also find I2 = (0.33 * I) .. . Vo= I2 . . (b) v1 = I1

    @chaand.i the volt must be 3.33 but when see the fig of zener , the max volt is 2

    @JoãoVitorMC : if you consider zener as R=1phm resistor then this question would be much much simpler

    yes that's what i do, but this happens only then the voltage saw by the element is in the range -+2

    yup because in the first part the current source is too big and then zener limits the voltage
