A resistor R, inductor L and capacitor C are connected in series to a power supply that is operating at the resonant frequency of the circuit. If another capacitor C is placed in series with the previous capacitor without changing anything else, the phase angle in the new circuit is . .

A. -90° < φ < 0 meaning current leads voltage
B. 0 < φ < 90° meaning voltage leads current
C. -90° < φ < 0 meaning voltage leads current
D. 0 < ф < 90° meaning current leads voltage
E. φ = 0 meaning voltage is in phase with current
