Question

Difference between ac and dc load line in table

Answer 1

Answer:

DC Load Line

DC Load Line

The DC Load Line is the locus of all possible operating point at which BJT remains in active region.

➨If base current IB < Icsat/β then transistor operates in active region.

➨If IB > Icsat/β , then it operates in saturation region.

➨Collector current Ic = Vcc-Vce/Rc as depicted in the figure-1. At saturation, Vce = Vces

Vce = Vcc at cutoff when Ic = 0 , Maximum value of current Icmax = Vcc/Rc

This is the ideal case. The Ic vs Vce curve along with load line
