TextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbookTextbook

Answer 

Given that current I = 12A

Time t = 1 hour

= 60min

= 3600sec

Charge Q = ?

We know that I= Q/t

Q = I*t

= 12*3600

= 43200C
                                        
Therefore the charge produced by a 12V battery in an hour is 43200C.
