dear friends


i m working on circuit analysis.



how i can take an output from from a point without changing work of circuit and give an input on that point. both input and output are same point. and they not effect to each other


Seems a contradiction in terms / usage. Take an arbitrary point in any circuit; you can call it and use it as an output - even if it is the input of an extremely sensitive operational amplifier, in which case do not expect much in the way of a useful signal. Take that same point (or any other) and call it an input and then ignorantly drive it with a signal of some sort. Doing so may damage components connected to and electrically nearby that point; not exactly a bright idea. define exactly what you want to do and give a circuit.
