# Question: Car batteries are often rated in ampere hours or A

Car batteries are often rated in “ampere-hours” or A ∙ h.

(a) Show that the has units of charge and that 1 A ∙ h = 3600 C.

(b) A fully charged, heavy-duty battery is rated at and can deliver a current of 5.0 A steadily until depleted. What is the maximum time this battery can deliver that current, assuming it isn’t being recharged?

(c) How much charge will the battery deliver in this time?
