Electromagnetic Induction And Alternating Current Ques 71

71. A series $R-C$ circuit is connected to AC voltage source. Consider two cases; $(A)$ when $C$ is without a dielectric medium and $(B)$ when $C$ is filled with dielectric of constant 4. The current $I_{R}$ through the resistor and voltage $V_{C}$ across the capacitor are compared in the two cases. Which of the following is/are true?

(a) $I_{R}^{A}>I_{R}^{B}$

(b) $I_{R}^{A}<I_{R}^{B}$

(c) $V_{C}^{A}>V_{C}^{B}$

(d) $V_{C}^{A}<V_{C}^{B}$
