For a transmission line open circuit and short circuit impedances are ...
The characteristic impedance is the geometric mean of the short and open circuit impedance. It is given by Zo2 = Zsc Zoc. On substituting Zoc = 20 and Zsc = 5, we get Zo2 = 20 X 5 = 100. Thus Zo = 10 ohm.

For a transmission line open circuit and short circuit impedances are ...
Ohm and 5 Ohm respectively. These values indicate the impedance of the transmission line when it is either open-circuited or short-circuited at the end.
Impedance is the measure of opposition to the flow of current in an electrical circuit. In the case of a transmission line, it is the characteristic impedance of the line. When the line is open-circuited, the impedance offered by the line is 20 Ohm, which means that it resists the flow of current with an impedance of 20 Ohm. Similarly, when the line is short-circuited, the impedance offered by the line is 5 Ohm, which means that it resists the flow of current with an impedance of 5 Ohm.
The open circuit and short circuit impedances of a transmission line are important parameters that affect the performance of the line. They determine the reflection coefficient and the attenuation of the line, which in turn affects the efficiency and quality of the signal transmission. Therefore, it is important to accurately measure and characterize the open circuit and short circuit impedances of a transmission line to ensure optimal performance.
