Hi guys, this is my first post in this forum so I hope I get some help.
My question is: can an output voltage of ANY circuit be larger than its input/source voltage. I realize that in DC circuits, this is not possible because of KVL. Since the total voltage around a loop has to be zero and the fact that voltage across resistors is always positive.
However, can this (Output swinging higher than the input) happen in AC circuits. This really pisses me of, because sometimes out college professors speak about "voltage drops" in AC circuits and yet they say that the output voltage CAN go larger than its input. For example in power systems, they say that the voltage at the load can be larger than that at the generator side. Can somebody please help me understand this point.
