Hi shayaan
Don't worry about it . i will tell you how to do it ! but at first step write AV . we will convert it to the S form . ok ?

Hi jestin
Do you know how much power we are referring to ?
 

OK sir thank you sir.,

You have given me two circuits.

Voltage gain (Av)= Vo/Vi
For 1st circuit,
Av = C/Vi

For 2nd circuit,
Av = RL/Vi
 

No no no ! you are in wrong way . a guidance : as you probably know , xc=1/jwc ok ? and xl = jwl ok ? can you use the action like dividing voltage , from input to the out put ? ( are you familiar with : how to calculate impedance of a circuit ? if yes . a division between an impedance and another impedance . for example suppose that we have two resistor R1 and R2 . VR1=vout ( for instance ) .
Then vout = vin *( R1/R1+R2 ) . so you can use an action such as this , in this example . ok ?
 

OK so you mean I have to use voltage divider. OK I try.

OK so you mean I have to use voltage divider. OK I try.
 

For first circuit we have two impedance, Zc(capacitor) and ZL(inductor)

Vo=(Zc)/(ZL+Zc) * Vi

Is it right sir?

If no just tell me. I want to try it myself you just guide. Don't post solution.
 

OK.

Vo = (1/jwC)/{(1/jwC)+jwL} * Vi

Vo = Vi/{(jwC)(1/jwC+jwL)}

Sir I don't know how to simplify it more. :S
 

OK sir I got it.

BTW: I have to go now sir. But you post what you want I will see it at morning and I will post answer. Good morning sir.
 

to simplify it ! think on J^2 ! what will be the result . and try to remove a common part ! good morning my friend ! see good dreams ! see you later .
 

Hello sir.

I was waiting for your answer. I post my solution if you reply to my post#378. I also got the same answer in your above post. Yes I have done it.
