Question

What is significance of load line in bipolar junction transistor?

Answer 1

In graphical analysis of nonlinear electronic circuits, a load line is aline drawn on the characteristic curve, a graph of the current vs the voltage in a nonlinear device like a diode or transistor. ... In aBJT circuit, the BJT has a different current-voltage (IC-VCE) characteristic depending on the base current.

Transistor load line

• The load line diagram at right is for a resistive load in a common emitter circuit. The load line shows how the collector load resistor (RL) constrains the circuit voltage and current.
