lucky12345 congrats....could you give me the formula for q1..A and B also R, V. I....im stuck mannn

- anonymous

Assuming that I=9A, what is the value of the voltage vo (in Volts)?

- anonymous

Now assuming that I=−3A, what is the value of the voltage vo (in Volts)?
Finally, for the last two parts assume that I=4A.

- Qaisersatti

what are the formula for Q1

- anonymous

@lucky12345 could you help me with q1 q3 q6 please

- anonymous

midterm q1
current through R1 =current through R2 =(V1-R3(I1-I2))/(R1+R2+R3)
current through R3 =(V1-(R1R2)(I1-I2))/(R1+R2+R3)
1. Va=(current through R2)*R2+Vb
2. Vb=(current through R3 )*R3
3. power in R1= current through R1*current through R1*R1
4. power in R2=current through R2*current through R2*R2
5. power in R3=current through R3*current through R2*R3
6. power in V1=V1*current through R1
7. power in i1=Vb*current through R3
8. power in i2=-Vb*current through R3

trust me
just go for these answers

@lucky12345 , thanks a heap brother for question 1

- anonymous

The circuit elements have the following values: Vin=42V, R1=4Ω, R2=4Ω, R3=7Ω, A=1.5 and B=0.125. for midterm6 if you know

- anonymous

if u find it helpful click best response

- anonymous

@lucky12345 , Thanks bro ! kindly , post the formulas used in question 6 ?

- anonymous

congrats pls give formulae for q3 of midterm!!!!!

- anonymous

thak you may ask for midterm 5 Here, VS=90V, R=6kΩ, and the transistor parameter f=0.5mAV3. The amplifier is biased with VIN=2V. that Vout=Vs-(f*(VIN^3))*R is this right

- anonymous

ya its right

- anonymous

congrats pls give formulae for q3 of midterm!!!!!

- anonymous

@lucky12345 , Thanks bro ! kindly , post the formulas used in question 6 ?

- Qaisersatti

what abt Q2 and 3...:)

- anonymous

@lucky12345 , Thanks bro , but what about the last part of question 6 ??

- anonymous

@Qaisersatti
q2 is the most simple one
just refer HW3P1
u will find the answer there with solution

- Qaisersatti

thanks brother....actually i am travelling thats why i asked i will go to H3P1

- anonymous

Rth for thevelin have a formula

- anonymous

@ppich , can u tell me the formula for question 6 , the last part ???

- anonymous

but what about the other part @ppich for Q5

- benzo

lucky q1 (6-(1000*400)(2-2))/(1000+400+600) it said invalid syntax.......i was following what you post (V1-(R1R2)(I1-I2))/(R1+R2+R3)

- anonymous

@lucky12345 buddy for the first question i get the last two bits as incorrect could you help me out please

- anonymous

@ppich hey buddy seems that we both have the same values so could you please help me out!! i would be grateful to youy

- anonymous

thanks a lot @ppich

- anonymous

@muthukrishna241994 : power through i1= vb*I1
power by i2 = -vb*i2

- benzo

ali_amjad please help....what v1 the formula please

- benzo

midterm q2 formula please appreciate your help anyone?

- anonymous

@benzo do you got answers for Q1 and Q2 completely??

- benzo

what question ali

- anonymous

RTH please, Vin=18V, R1=1.5Ω, R2=3Ω, R3=4Ω, A=1.5 and B=0.5.

- anonymous

Rth=3.6

- anonymous

@joaoVitorMC If u got correct plz click the best response :D

- anonymous

@benjo
current through R3= (V1-(R1+R2)*(I1-I2))/(R1+R2+R3)

- anonymous

@lucky12345 , please tell us how to find Rth for question 6 ????

- anonymous

what are your values of q6

- anonymous

Please Brother , tell us the formula for it .... I have reached very close , Rth = Vth/Isc ... But just let us know the expression/formula for 'Isc' , so that everyone else can do it ... Thanks

- anonymous

its realy complicated
tell me your values

- anonymous

what is rth for v=15, r1=0.5, r2=1.5, r3=5, A=2, B=1.5

- anonymous

@lucky12345 .....Please tell me how to calculate Rth.....my values are V in =27V , R 1 =5Ω , R 2 =7Ω , R 3 =12Ω , A=6 and B=0.1

- anonymous

Please help with rth q6...only this part is left....

- anonymous

how to calculate Rth . and its Isc

- anonymous

ques no-4........can any one help me

- anonymous

how do you do Q3?

- anonymous

@epita tell me values of Q3

- anonymous

Assuming that I=10A,
Now assuming that I=−3A
Finally, for the last two parts assume that I=5A.

- anonymous

@epita
I = 10 . . . Vo =2
I = -3 . . . Vo =-1
I = 5 . . . V1 =3.333 . .. . V0= 1.667

- anonymous

Thanks a million!

- anonymous

welcome

- anonymous

I = 10 . . . Vo =2
I = -3 . . . Vo =-1
I = 1 . . . V1 =? . .. . V0= ? pls tell for i=1
