Alternating CurrentHard

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 IR through the resistor and voltage VC across the capacitor are compared in the two cases. Which of the following is/are true?

Options

A.
B.
C.
D.

Solution


V2 = VR2 + VC2 = (IR)2
