🎯 Hear from the experts why preparing for JEE/NEET today sets you up for future-proof, high-income careers tomorrow.
An Intiative by Sri Chaitanya

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 180o ahead of phase of the current in the circuit

d

The quality factor of the circuit is  ωL/R or 1/ωCR  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

answer is D.
