Question
(II) What is the total amount of energy stored in a 12-V, 65 A $\cdot$ h car battery when it is fully charged?
Step 1
We know that 1 ampere hour is equal to 3600 ampere seconds (or coulombs), so we multiply 65 ampere hours by 3600 to get the charge in coulombs: \[Q = 65 \, \text{A} \cdot \text{h} \times 3600 \, \text{s/h} = 234000 \, \text{C}\] Show more…
