Okay, I'm stumped with NCEES practice problem 120. I have a background in power design, so I'll admit that amplifiers are a weak point for me, so I apologize if this is a dumb question.
Looking at the problem, it has an amplifier circuit with a resistor and capacitor attached. You have to figure out the bode plot for A=V1/V2 versus frequency, where V1 is the input voltage and V1 is output voltage.
From the what the solution says: A=(1/jwC)/®=1/RCw, it looks to me like they're saying that V1=1/jwC and V2=R. This is what's confusing me. Maybe the current is the same and cancels out in the numerator and denominator?
Thanks in advance to anyone who can help explain this! I have the EERM, but can't find anything in it that helps me with this.
