The label on a 12.0-V truck battery states that it is rated at 150.0 A·h (ampere-hours). Treat the battery as ideal.
(a) How much charge in coulombs can be pumped by the battery? [Hint: Convert A·h to A·s.]
C
(b) How much electric energy can the battery supply?
J
(c) Suppose the radio in the truck is left on when the engine is not running. The radio draws a current of 2.20 A. How long does it take to drain the battery if it starts out fully charged?
hours
