AIIMS 2017 | Alternating Current Question 7 | Physics

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 two cases.

$$I_R^A> I_R^B$$

$$I_R^A< I_R^B$$

$$V_C^A< V_C^B$$

None of these
