Question

Match List - I with List - II (Value of reflection coefficient).

List - I	List - II
A. Short circuit B. Open circuit C. Line characteristic impedance D. 2 times of line characteristic impedance	I. 0 II. -1 III. +1 IV. +\dfrac{1}{3}

• A. A-II, B-III, C-III, D-IV
• B. A-IV, B-III, C-I, D-II
• C. A-II, B-III, C-I, D-IV
• D. A-IV, B-I, C-III, D-II

Hint:

Reflection coefficient: \[ \Gamma=\frac{Z_L-Z_0}{Z_L+Z_0} \] Important special cases: \[ Z_L=0 \Rightarrow \Gamma=-1 \] \[ Z_L=\infty \Rightarrow \Gamma=+1 \] \[ Z_L=Z_0 \Rightarrow \Gamma=0 \]

Answer 1

The Correct Option is C
