Q.

What happens to the h parameters of a transistor when the operating point of the transistor changes?

A. it also changes
B. does not change
C. may or may not change
D. nothing happens
Answer» A. it also changes
Explanation: it is very difficult to get exact values of h parameters for a particular transistor. it is because these parameters are subject to considerable variation unit to unit variation, variation due to change in temperature and variation due to the operating point.
