Correct:
C
Explanation
To find the amount of electric charge (Q) flowing through a circuit, the standard formula used is Q = I × t, where 'I' represents the electric current in Amperes (A) and 't' represents the time in seconds (s). In this problem, the current (I) is given as 0.6 A and the time (t) is 10 minutes. Since the SI unit for time in this calculation must be seconds, 10 minutes is converted by multiplying by 60, resulting in 600 seconds. Applying the formula: Q = 0.6 A × 600 s = 360 C. Therefore, the total electric charge that flows through the circuit is 360 Coulombs. This relationship is derived from the definition of electric current as the rate of flow of electric charges through a particular area in unit time.
