q6 the formula 1Vo* (R3(B*R1*R3)+R1+R2+A*R2)/(R3B*R1*R3)=VIN 2i1=V0/(R3B*R1*R3) 3 vo = vth but i don't know the RTH

what formulas did you use? My Resistances are 1ohm
 one year ago

Zozi Group TitleBest ResponseYou've already chosen the best response.0
just valculating v1, one 1 ohm and two serial resistors in paralel means a 0,66ohm resistor. From this U=I*R for v1 and for v0 its a half divider from two one ohm resistor...

sara do you mean I1= vin/(r3b*r1*r3 vo=vin*(r3(b*r1*r3)+r1+r2+a*r2)/(r3b*r1*r3)

Thank you once again zozi, it was v0= 0.666 and v1=1.32, it was the other way around Also, for you Joao Vitor, RTH = 3.6

I don't have formulas, sorry... I Only know that RTH = VTH / Isc and Isc is the current on short circuit. Zizo told me the values for Q3.

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

vivek2609 Group TitleBest ResponseYou've already chosen the best response.0
if you assume I=2A then the current through the parallel resistor will be 1.3333 A ant V1 will be(1ohm*1.333) 1.333V the remaining current flows through the zener diode its resistance will be 1ohm so v0 will be 0.667v
