Question

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?

Options:(select one or more)

Answer:

BD

Solution:

$C_{B} > C_{A}$

so $I_{R}^{A} > I_{R}^{B}$

and $V_{C}^{B} > V_{C}^{A}$
