Example Question #111 : Electrostatics
If the area of the plates of a parallel plate capacitor is doubled and the distance between the plates is halved, then the capacitance is __________.
Possible Answers:
halved
doubled
quartered
unchanged
quadrupled
Correct answer:
quadrupled
Explanation:
Capacitance is directly proportional to area of the parallel plates and indirectly proportional to the distance between the plates. So and area is doubled
and distance is halved
so the capacitance increases by a factor of 4.
