Current and charge in a battery. Consider a car battery rated at 100 A· h. This battery can supply a current of 100 A for an hour.
(a) How much charge can the battery supply?
(b) What must be the area of a parallel plate capacitor, with plates separated a distance d = 0.01 mm and relative permittivity of 4 for the dielectric between the plates to supply the same charge as the battery in (a)?
