Car batteries are typically rated in ampere-hours, or A · h.
(a) Show that ampere-hours are actually a unit of charge.
Determine the conversion from ampere-hours to coulombs.
(b) If a 114 A · h battery can deliver a steady current of 4.5 A until it is completely depleted, what is the total time the battery can deliver current without being recharged?
(c) How much total charge will the battery deliver in this time?
