A lossless 50 Ω transmission line is terminated 30 + j25 Ω, then voltage reflection coefficient and current reflection coefficient are

[A]. 062 ∠82.88, - 0.62 ∠82.88
[B]. 10.36 ∠11.296, - 10.36 ∠111.296
[C]. 0.23 ∠49.1, - 0.23 ∠ + 49.1
[D]. - 10.36 ∠111.296, 10.36 ∠111.296

Answer: Option D

Explanation:

Voltage reflection coefficient

Current reflection coefficient : ri = - rv = + 10.36 ∠111.296.
