Capacitors (Notes & Practice Questions)
Capacitance: This is the measure of a capacitor''s ability to store charge, expressed in farads (F). The capacitance C is given by: C = Q/V where Q is the charge stored, and V is the voltage across the capacitor. The capacitance depends on the surface area of the plates, the distance between them, and the properties of the dielectric material.

The capacitance of a capacitor lled with a dielectric is given by C= C 0, where C 0 = Q= V 0 is the capacitance in the absence of the dielectric, and is the dielectric constant. The presence of a dielectric occupying the entire gap between the capacitor plates increases the capacitance by a factor .
