Decide whether each of these statements is True (T) or False
With a series RCL circuit, at resonance:
(i) The voltage phasor for the capacitor is oppositely directed and equal in size to that of the inductor.
(ii) The circuit impedance is equal to the value of the resistance.
A) (i) T (ii) T
B) (i) T (ii) F
C) (i) F (ii) T
D) (i) F (ii) F

(i) At resonance, the reactance of the inductor and the capacitor cancel out, resulting in equal and oppositely directed voltage phasors for both components.
(ii) At resonance, the circuit impedance is purely resistive, and therefore equal to the value of the resistance.
