The current intensity is defined as the amount of charge flowing through a certain point of a wire divided by the time interval:
[tex]I= \frac{Q}{\Delta t} [/tex]
where Q is the charge and [tex]\Delta t[/tex] is the time. Re-arranging the formula, we have
[tex]Q=I \Delta t[/tex]
for the compressor in our problem, the intensity of current is I=66.1 A, while the time is [tex]\Delta t= 0.388 s[/tex], so the amount of charge that crosses a certain point of the circuit during this time is
[tex]Q=I \Delta t=(66.1 A)(0.388 s)=25.65 C[/tex]
