The experiment that follows is carried out to determine the thevenin’s theorem experimentally thevenin’s theorem is an equivalence principle in circuit theory.
Network theorems network analysis methods two-port parameters s is replaced with jω and the more familiar values from ac network theory result. A circuit is linear when superposition theorem can be used to obtain its currents and voltages when this theorem is applied to an ac circuit, it has to be remembered.

Any linear electrical network with voltage and current sources and resistances only can be it means the theorem applies for ac in an exactly same way to dc except.
In its simplest form, the reciprocity theorem states that if an emf e in one branch of a reciprocal network produces a current i in another, then if the emf e is moved.
