ECE 3025C -- Electromagnetics Thevenin Equivalent Circuit Example Problem Consider the following circuit consisting of a generator, transmission line, and a resistive load at the end of the transmission line: The switch is thrown at 0 t = and Τ is the one way propagation time in the transmission line. Calculate the Thevenin equivalent circuit for time in the range 3 t Τ ≤ ≤ Τ . This is equivalent to finding TH R and TH V for the circuit below:
