Which of the following parameters signifies the relation of collector current to collector voltage keeping source voltage as constant ?

Which of the following parameters signifies the relation of collector current to collector voltage keeping source voltage as constant ?

a. Input Impedance
b. Output admittance
c. Voltage & Current Gain
d. Output Impedance

Correct Answer : b. Output admittance

Explanation :

The ratio of current to voltage measures only by admittance while impedance measures ratio of voltage to current & ( voltage & current gain ) simply measures same voltage and current ratios respectively.
