A series R-C circuit is connected to an AC voltage source. Consider two cases: (A) when C is without a dielectric medium and (B) when C is filled with a dielectric of constant 4. The current $I_R$ through the resistance and voltage $V_C$ across the capacitor are compared in the two cases. Which of the following is true?

A

$I_R^{A} > I_R^{B}$

B

$I_R^{A} < I_R^{B}$

C

$V_C^{A} < V_C^{B}$

D

None of these

Accepted Answer

$I_R^{A} < I_R^{B}$

Answer

$I_R^{A} > I_R^{B}$

Answer

$V_C^{A} < V_C^{B}$

Answer

None of these
