A) The circuit is at resonance and its impedance is made up only of a reactive part
B) The current in the circuit is in phase with the applied e.m.f. and the voltage across R equals this applied emf
C) The sum of the p.d.?s across the inductance and capacitance equals the applied e.m.f. which is \[{{180}^{o}}\] ahead of phase of the current in the circuit
D) The quality factor of the circuit is \[\omega L/R\] or \[1/\omega CR\] and this is a measure of the voltage magnification (produced by the circuit at resonance) as well as the sharpness of resonance of the circuit
