Question
Car batteries are typically rated in ampere-hours, or A · h. (a)Determine the conversion from ampere-hours to coulombs.
1 A · h = 1 C
(b) If a 137 A · h battery candeliver a steady current of 4.5 Auntil it is completely depleted, what is the total time the batterycan deliver current without being recharged?
2 h
(c) How much total charge will the battery deliver in thistime?
3 C (a)

(b) If a 137 A · h battery candeliver a steady current of 4.5 Auntil it is completely depleted, what is the total time the batterycan deliver current without being recharged?
2 h
(c) How much total charge will the battery deliver in thistime?
3 C
Explanation / Answer
(a)the conversion from ampere-hours to coulombs. 1A.h=1*3600s=3600 C (b) the total time the battery can deliver currentwithout being recharged t=137A.h/4.5=30.44 h (c) total charge will the battery deliver in this time Q=3600*137=493200 C
