Vedclass · Answer

(D) In a series $LCR$ circuit connected to an $A.C.$ source:$1$. In a pure resistor $(R)$, the current and voltage are always in phase.$2$. In a pure inductor $(L)$, the voltage leads the current by a phase angle of $90^{\circ}$ ($\pi/2$ radians), meaning they are out of phase.$3$. In a pure capacitor $(C)$, the current leads the voltage by a phase angle of $90^{\circ}$ ($\pi/2$ radians), meaning they are out of phase.Therefore, in both the inductor $(L)$ and the capacitor $(C)$, the current and voltage are out of phase with each other. Thus, option $D$ is correct.

$L$, $C$ and $R$ are connected in series to an $A.C.$ source. Which one of the following is true? Phase relation between current and voltage is such that
