In a RLC circuit, a second capacitor is connected in series with the capacitor previously in the circuit. What is the effect of this change on the impedance of the circuit?
A) It increases.
B) It decreases.
C) It does not change.
D) It increases for frequencies below resonance and decreases for frequencies above resonance.
E) It decreases for frequencies below resonance and increases for frequencies above resonance.
