JEE Advanced 2011 Physics 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 through the resistor and voltage across the capacitor are compared in the two cases. Which of the following is/are true?
Answer: (B),(C)
Solution
Filling the capacitor with a dielectric of constant 4 makes , so . Current : a smaller gives a larger current, so (B
