The motor in a battery-powered model train draws a steady current of 0.65 A for 40 s. The charge transferred is calculated using Q=ItQ=ItQ=It, where Q Q\,Q is charge, I I\,I is current and t t\,t is time.
Calculate the total charge passing through the motor during this interval. Give the unit of your answer.
