Capacitors (2)
•Capacitance C is the ratio of the charge q on one plate of a capacitor to the voltage difference v between the two plates, measured in farads (F).
•Where e is the permittivity of the dielectric material between the plates, A is the surface area
of each plate, d is the distance between the plates.
•Unit: F, pF (10–12), nF (10–9),
and
and
mF (10–6)
