List-I	List-II
A. Z-parameters B. Y-parameters C. h-parameters D. ABCD-parameters	I. Short circuit admittance II. Open circuit impedance III. Hybrid parameters IV. Transmission parameters

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

Hint:

Important two-port parameter names: \[ Z \rightarrow \text{Open circuit impedance} \] \[ Y \rightarrow \text{Short circuit admittance} \] \[ h \rightarrow \text{Hybrid parameters} \] \[ ABCD \rightarrow \text{Transmission parameters} \]

Answer 1

The Correct Option is B

Concept: Two-port networks are represented using different parameter systems depending upon convenience of analysis. Important parameter sets include:
• Z-parameters
• Y-parameters
• h-parameters
• ABCD-parameters Each parameter system has a standard name and physical interpretation.

Step 1: Match Z-parameters. Z-parameters are called: \[ \text{Open circuit impedance parameters} \] Thus: \[ A \rightarrow II \]

Step 2: Match Y-parameters. Y-parameters are called: \[ \text{Short circuit admittance parameters} \] Thus: \[ B \rightarrow I \]

Step 3: Match h-parameters. h-parameters are called: \[ \text{Hybrid parameters} \] Thus: \[ C \rightarrow III \]

Step 4: Match ABCD parameters. ABCD parameters are called: \[ \text{Transmission parameters} \] Thus: \[ D \rightarrow IV \]

Step 5: Write final matching sequence. Therefore: \[ A-II,\ B-I,\ C-III,\ D-IV \] Hence, the correct option is: \[ \boxed{(A)\ A-II,\ B-I,\ C-III,\ D-IV} \]
