Question

The ratio of the current transform at one port to current transform at other port is called ____.

• A. Transfer admittance
• B. Transfer impedance
• C. Current transfer ratio
• D. Voltage transfer ratio

Hint:

Two-Port Network Ratios. Output/Input: Voltage/Voltage = Voltage Ratio; Current/Current = Current Ratio; Voltage/Current = Impedance; Current/Voltage = Admittance. "Transfer" usually implies relating output at one port to input at the other.

Answer 1

The Correct Option is C

In the analysis of two-port networks, various parameters relate the voltages and currents at the input port (port 1) and the output port (port 2)
- Voltage Transfer Ratio (Voltage Gain): Ratio of output voltage to input voltage (V\(_2\)/V\(_1\))
- Current Transfer Ratio (Current Gain): Ratio of output current to input current (I\(_2\)/I\(_1\))
- Transfer Impedance: Ratio of voltage at one port to current at the other port (e
g
, V\(_2\)/I\(_1\))
- Transfer Admittance: Ratio of current at one port to voltage at the other port (e
g
, I\(_2\)/V\(_1\))
The question asks for the ratio of current at one port to the current at the other port
This is, by definition, the Current Transfer Ratio
(Note: "current transform" likely means the Laplace transform of the current, but the ratio definition holds)
