The reflection co-efficient at the open circuited end of a transmission line___________?
Correct answer: C. unity
- A. zero
- B. infinity
- C. unity
- D. none of the above
Explanation
At an open circuit, the load impedance is infinite, so the voltage reflection coefficient is (ZL − Z0)/(ZL + Z0) = +1. Its magnitude is therefore unity, while the current reflection coefficient would be −1.
