Question

Vin=45V, R1=1.5Ω, R2=2Ω, R3=6Ω, A=2 and B=0.5
what is the RTH ?

Answer 1

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

Answer 2

Tell me the othersQ6 answews, pls.. I have the same values

Answer 3

5
7.5
7.5

Answer 4

She/He wrote that and its correct only if you have those values.

Answer 5

I have the same values. and did you get the RTH?

Answer 6

not yet

Answer 7

@benzo
1-Vo* (R3-(B*R1*R3)+R1+R2+A*R2)/(R3-B*R1*R3)=VIN
2-i1=V0/(R3-B*R1*R3)
3- vo = vth
this is the formula of q6
did you mean that ?

Answer 8

do you guys have any news abt the rth?

Answer 9

yeah....I saw sum1 had postd d formula...
Its Vth/Isc...
Bt don knw how to calculate Isc.. :P
Can sumbdy help me out pls.?

Answer 10
