    [​IMG] Hi guys can you please remind me on how to get started with this? It's been a little bit since I've done one and my book is only offering solutions based on using the impedance. I really don't prefer that method and I like using node voltage and have had plenty of success doing so I jut can't recall what happens at node B. Is it the same voltage as A? So my Equation there would be (A - Vi)sC + A/R2 ? I seem to remember thinking that it should equal zero and if I do that then the first part of the equation is fine but the second part is eluding me, -Vi(sC) + ???
    Thanks guys!!!
