Question:
In a transmission line with a characteristic impedance \( Z_0 \), what happens if the load impedance \( Z_L \) matches \( Z_0 \)?
In a transmission line with a characteristic impedance \( Z_0 \), what happens if the load impedance \( Z_L \) matches \( Z_0 \)?
Show Hint
Impedance matching is crucial in transmission lines to ensure maximum power transfer to the load without reflections.

- Maximum power is transferred to the load
- No power is transferred to the load
- Half of the power is transferred to the load
- The voltage across the load is maximum
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
When the load impedance \( Z_L \) matches the characteristic impedance \( Z_0 \) of the transmission line, maximum power transfer occurs. This condition ensures that the impedance is perfectly matched, minimizing reflections and maximizing the energy delivered to the load.
