Question

1.Car batteries are typicallyrated in ampere-hours, or A · h. (a) Show that ampere-hours areactually a unit of charge. (Do this on paper. Your instructor mayask you to turn in this work.)

Determine the conversion from ampere-hours to coulombs.
1 A · h = C

(b) If a 74 A · hbattery can deliver a steady current of 8.0 A until it is completely depleted, whatis the total time the battery can deliver current without beingrecharged?
h

(c) How much total charge will the battery deliver in thistime?

Explanation / Answer

the conversion from ampere-hours to coulombs 1A.h=1*3600s=3600C (b)the total time the battery can deliver current withoutbeing recharged time=Q/I=74A.h/8A=9.25h (c) total charge will the battery deliver in thistime Q=74A.h=74*3600s=266400C
