In a series LCR circuit fed with an alternating emf E = E0 sin ωt, (a) the voltage across L is in phase with the applied emf E.

Question 1

In a series LCR circuit fed with an alternating emf E = E0 sin ωt,

(a) the voltage across L is in phase with the applied emf E.

(b) the voltage across C is in phase with the applied emf E.

(c) the voltage across R is in phase with the applied emf E.

(d) the voltages across L, C and R are all in phase with the applied emf E.

Question 2

Usually, VR, VL, VC are not in phase with E, if in resonance, then only E will be in phase with VR.

∴ No option is correct.
