Question

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.

Answer 1

Usually, V_R, V_L, V_C are not in phase with E, if in resonance, then only E will be in phase with V_R.

∴ No option is correct.
