If a transmission line of length less thanλ/4isshort circuited,...
One-tenth of the wavelength is used to transmit a signal, then the line can be considered as a lumped element. This means that the transmission line can be modeled as a series of discrete components, such as resistors, capacitors, and inductors, that are connected in a particular configuration to achieve the desired signal transmission characteristics.
In this lumped element model, the transmission line is assumed to have uniform characteristics along its entire length, and the signal propagates through the line instantaneously. This approximation is valid for low-frequency signals and short transmission lines, but it becomes less accurate as the frequency and length of the transmission line increase.
For higher frequency signals or longer transmission lines, a distributed element model must be used to accurately describe the signal propagation. In this model, the transmission line is considered as a continuous medium with varying characteristics along its length, and the signal is modeled as a wave that travels through this medium. The distributed element model is more complex than the lumped element model, but it provides a more accurate description of signal transmission in high-frequency and long-distance applications.

If a transmission line of length less thanλ/4isshort circuited,...
For a transmission line , the length is considered
lambda / 4 or lambda / 2
hence for lambda /4 is short circuited the circuit will behave as a pure inductive reactance
lambda / 4 or lambda / 2
hence for lambda /4 is short circuited the circuit will behave as a pure inductive reactance
