What is the significance of surge impedance and surge impedance loading? What do they mean, and why are they important?
Homework Answers
The theoretical significance of the surge impedance is that if purely resistive load is equal to the surge impedance were connected to the end of the transmission line with no resistance, voltage surge is introduced to the sending end of the transmission line which is completely absorbed at the receiving end
