##Part A Given a parallel RLC circuit with R = 20\, k\Omega and L = 0.6\, \muH.

What value of C [in F] will make the circuit critically damped?

What is the characteristic impedance [in \Omega] of this system, for the C determined above?

What value of C [in F] will result in an underdamped response with Q = 10?

##Part B For the circuit below, determine the value of R needed to have a critically damped response.

What value of R [in \Omega] will make the circuit critically damped?
