What is the equivalent resistance as an algebraic expression (in terms of R) of network as C viewed from its port?
I tried thinking of it as the two parallel resistors being one 1/2 R series resistor, then adding them up, giving 5/2*R.
I also tried thinking of it as parallel of two series resistors, giving R
both were incorrect
I think my failure to grasp the concept of "nodes" has something to do with this, the question looks nothing like the other combination circuit tutorials I found online, can someone give me a intuitive or easy to understand way to understand this question?
