The charge (Q) that passes through a machine is given by the product of the current (I) and the time (t) for which the current flows: Q = I * t.
The current is given in Amperes (A), and the time must be in seconds (s) to get the charge in Coulombs (C). The given time is 10 minutes, which is 10 * 60 = 600 seconds. The current is 15 A.
Calculating the charge: Q = 15 A * 600 s = 9000 Coulombs. This represents the total amount of electric charge that flows through the electrical machine over the 10-minute period.
