A capacitor, inductor and resistor are connected in series across an AC source. When the source frequency is f, the phase angle is positive (> 0, where the phase angle is defined to be positive if the voltage leads the current). Which best describes the frequency frelative to the resonance frequency fo? f< fo f = fo f> > fo The frequency could be any of the above.
