Q. The value of aac for all practical purposes, for commercial transistors range from_

A
0.5-0.6
B
0.7-0.77
C
0.8-0.88
D
0.9-0.99
Solution:

For all practical purposes, aac=adc=a and practical values in commercial transistors range from 0.9-0.99. It is the measure of the quality of a transistor. Higher is the value of a, better is the transistor in the sense that collector current approaches the emitter current.
