rd=100*10^3//rd=drain resistance in ohms
gm=3500*10^-6//gm=transconductance in terms of A/V (or S)
RL=5*10^3//RL=load resistance in ohms
u=rd*gm//u=amplification factor
AV=(u*RL)/(((u+1)*RL)+rd)//AV=voltage gain
format("v",6)

format("v",6)
disp("ohm",floor(Ro1),"The output resistance including RL is=")//floor function is used to round down the value
