Dc Load Line Of Transistor. Transistor load line variations (approximate for 2n2222) characteristic curves: A bjt load line, or a bipolar junction transistor, provides for both electrons and electron holes as charge carriers.

Transistor load line variations (approximate for 2n2222) characteristic curves: This line is called as d.c. When the transistor is given the bias and no signal is applied at its input, the load line drawn at such condition, can be understood as dc condition.
