load line


Joined Feb 24, 2006
what is the difference between a load line and a characterstics curve, because both are the plot between Vce and Ic (for a common emitter ) .
A load line is unique to the load resistor in a given circuit. The characteristic curves are properties of the transistor independent of the values of any external comnponents. In the characteristic curves, the base current is a parameter which is held constant on each curve.
