We had to find V(in)/V(out):
The circuit given is RLC circuit with varying frequency of VOLTAGE(V(in)).
The correct solutions of the question considered
Impedance= Resistance +R(l)+R©
Now that’s the thing I don’t understand
Isn’t Impedance = sqrt(r*r+(R(l)-R©)^2)
now this equation will have it’s minima at s=1/sqrt(R(l)*R©)
Resulting in itf= r/R©=r*sqrt(c/l)
I don’t understand where I am going wrong.
