What is the area of the plates of a 0.1 µF parallel plate air capacitor, given that the separation between the plates is 0.1 mm.

What are the factors on which the current depends at resonance?

Name the factor on which inertia depends.

How capacitance changes if the distance between the plates of a parallel plate capacitor is halved?

Show that the force on each plate of a parallel plate capacitor has a magnitude equal to (1/2)QE, where Q is the charge on the capacitor and E is the magnitude of electric field between the plates. Explain the origin of the factor (1/2).
