EXP-2-NORTON'S THEOREM

Any two terminal Linear Network containing energy sources and impedances can be replaced by an equivalent circuit containing of a Current Source (In) parallel with an Admittance (Yn). Y = 1/Z Z = R Current in Z4 in this circuit is equal to the Current in Z4 in Thevenin Circuit. Rn = Rt I1 = Vt / Zt
