These are considered here for different input values to obtain different output curves. In the above figure, the output characteristics are drawn between collector current I C and collector voltage V CE for different values of base current I B.

When the output characteristics of a transistor are considered, the curve looks as below for different input values. The outputs of the transistor are the collector current and collector voltages. But among all these regions, we have found that the transistor operates well in active region and hence it is also called as linear region.

Till now we have discussed different regions of operation for a transistor.
