Hello
I don't quite understand what does the question mean
So I ask my teacher and he tells me draw the load line first
I try to write down the dc and ac load line equation.
dc:
Id=-Vds/(Rd+Rs) + Vdd/(Rd+Rs)
Id=-Vds/5000 +12/5000
ac:
Vds=Vd-Vs
Vds=-id*(Rd//RL)-id*Rs
id=-Vds/3500
I put Vds=0 and Id=0 to dc load line equation
then I get the x-intercept and y-intercept
But I put Vds=0 and Id=0 to ac load line equation
I get both 0 at LHS and RHS
How to find the x and y intercept and plot the ac load line?
