Question

The circuit elements have the following values: Vin=27V, R1=5Ω, R2=7Ω, R3=12Ω, A=6 and B=0.1

Answer 1

i am not sure about the above values..i still need to check :p

Answer 2

Rth????

Answer 3

rth=vth/isc

Answer 4

isc formula plzzz gyuz

Answer 5

@1431mahi
i1=Vo/(R3-(B*R1*R3)
Vo=(Vin*(R3-B*R1*R3))/(R3-(B*R1*R2)+R1+R2+(a*R2))
Vth=Vo
Rth=Vth/Isc
put Isc=0.25

Answer 6

Isc = 0.25 . . how??

Answer 7

Isc is the short circuit current.....
short the independent voltage source and find the current entering from the output port...

Answer 8

@neelima and what about dependent sources

Answer 9

Rth=10.8
vo=2.7

Answer 10

@akash97 how you have Rth . . what are the circuit parameters

Answer 11

@ali_amjad : deondnt sources cant be replaced by der intrnal resistances

Answer 12

the following values:
Vin=15V,
R1=0.5Ω,
R2=1.5Ω,
R3=5Ω,
A=2
and B=1.5.
my answer :
3
3
2.4
Rth ?? Isc??

Answer 13

@akash97 any hint now??

Answer 14

@ali_amjad : short ckt d o/p terminal n get Isc

Answer 15

Shorted it and also R3 will have no effect now??

Answer 16

@ali_amjad : find currnt through dt mesh

Answer 17

there two masehs?? one containg R3 and Bvb and second containg Ava and R1 R2?? correct
