Physics - EMI/AC Question with Solution | TestHub
A series - circuit is connected to voltage source. Consider two cases; when is without a dielectric medium and when 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?
Options:(select one or more)
Answer:
Solution:
In case (b) capacitance will be more. Therefore, impedance will be less. Hence, current will be more. Option (b) is correct. Further, In case (b), since current is more. Therefore, will be less. Option (c) is correct. Correct options are (b) and (c). Analysis of Question (i) Question is moderately difficult. (ii) In my opinion problems of alternating currents are not very difficult. (iii) Topic of is small. One can feel comfortable in this topic by putting less efforts.
