Bah ignore this...I thought I had D right for a moment... For D: For Av = vL/vs vs = iin(ri + Rs) μiin = μvin/Req where Req = RL + Ro μiin = μvin/(RL + Ro) Since the right loop of D is a series circuit, multiplying the output current on both sides by RL will yield vL on...

Gotcha, so referring to C: Av = vL/vs where: By Ohm's Law: vs = IRtotal = I(Rs + ri) So far then I have: Av = vL/I(Rs + ri) Then vL = μvin = μIinReq Where Req = RLro/(ro + RL) Then vL = μIin*RLro/(ro + RL) And now Av = μIin*RLro/vin[(ro + RL)(Rs + ri)] But vin/Iin...

For C: Then if I know the vin voltage, the amp. output voltage would just be μvin. But then by Kirchoff's loop law, since the load is in parallel with the amplifier output voltage, this would imply the load voltage, amplifier output resistor voltage and the amplifier voltage are equal. vL =...

I thought r_i would have mattered as it is used in the voltage divider rule to figure out the input voltage of the amplifier and from there mu*v_in would have been the output voltage of the amplifier. If I considered the first loop in C then we have: Vs = VSource Resistance + VAmp input...

r_i is a constant but I'll see where I get with your suggestions on C for now. It's just late here right now but I'm going back to it in the morning. Thank you very much.

Homework Statement I've been reviewing my electrical theory and I'm having trouble trying to calculate an expression for the voltage gain for these two specific circuits. (Images c and d of the question.png attachment). I already know the answers, however I am unable to derive the same...

I was using a 555 timer circuit to generate a tone the frequency of roughly 256 Hz with resistors of 22 and 270 Ohms and a capacitor of 10 uF but I was advised not to by my teacher and wasn't able to ask the reason why. Can someone kind of brief me on this since my teacher is away tomorrow and...

First of all I am not really that far into my physics knowledge (I'm still in high school). I have a projct to design an instrument and explain how is sound produced by my instrument. I was planning to make an electric instrument such as a synthesizer using my computer engineering course...
