Which of the following statement is/are true regarding infinite line:
- It maintains a constant voltage
- It has infinite length
- Both 1 and 2
- It has infinite voltage
Correct answer: 2. Both 1 and 2
Explanation: An infinite transmission line is a theoretical concept used in electrical engineering to analyze the behavior of transmission lines. Regarding the given options:
- It maintains a constant voltage:
- True. In an infinite transmission line, the voltage is assumed to remain constant along its length. This is based on the assumption that the line is lossless and there are no impedance mismatches.
- It has infinite length:
- True. The term “infinite” in the context of an infinite transmission line refers to the theoretical consideration that the line extends indefinitely. It is a simplification used in mathematical analysis to model transmission line behavior over long distances.
Therefore, the correct answer is “Both 1 and 2.” The infinite line is a theoretical concept used for analysis and does not exist physically, but it helps in understanding the principles of transmission lines.
