In which of the following transmission lines is capacitance effect negligible?
Short transmission lines transmission lines
Therefore, for simplification and practical analysis, the shunt capacitance of a short transmission line is considered negligible and is often ignored in the equivalent circuit model. Unlike short transmission lines, the capacitance effect is significant in medium and long transmission lines. Based on this analysis, the capacitance effect is considered negligible in short transmission lines. Therefore, the correct answer is Short transmission lines transmission lines.
