STANDARD Physics Capacitance MCQ Question
A parallel plate air capacitor has a capacitance C. When it is half filled (along the length of one plate) with a dielectric of dielectric constant 5, the percentage increase in the capacitance will be
400%
66.6%
33.3%
200%
Correct Answer
Detailed Explanation
The capacitance increases due to the dielectric. The effective capacitance is the average of the capacitance with and without the dielectric, leading to a 66.6% increase.
