a) Under what condition does X_{C} short out the lower portion of the voltage divider? When X_{C} is open, what is the result of the voltage divider?
b) Find the effective impedance of the parallel combination of R_{2} and C, then use the voltage divider formula to find an expression for the gain.
When there is both inductive and capacitive reactance present, what happens to the voltage divider at resonance? off-resonance?
I find:
