Answer / Kaushlendra Kannojiya

Thevenin's theorem states that for a linear two-port network, any combination of voltage and current sources can be replaced by an equivalent voltage (Vth) in series with an impedance (Zth). To find Vth and Zth, open the output port and calculate the open-circuit voltage (Vo) across the port and the total impedance (Ztot) looking into the open port. Then, Vth = Vo and Zth = Ztot.
