An ac generator with m = 220V and operating at 400 Hz causes oscillations in a series

An ac generator with ξ m = 220V and operating at 400 Hz causes oscillations in a series RLC circuit having R = 220Ω, L = 150mH, and C = 24.0μF. Find
(a) The capacitive reactance XC,
(b) The impedance Z, and
(c) The current amplitude I. A second capacitor of the same capacitance is then connected in series with the other components. Determine whether the values of
(d) XC,
(e) Z, and
(f) I increase, decrease, or remain the same.
