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 IR through the resistor and voltage VC across the capacitor are compared in the two cases. Which of the following is/are true? [2011]
a. IRA>IRB
b. IRA<IRB
c. VCA>VCB
d. VCA<VCB
