Seema switched on an electric circuit and went away to drink some water. She came back after 2 minutes and noticed that the circuit had 2.5 A of current flowing through it. The net charge that had flown through the circuit is:
300 C
Current (I) = 2.5 A Time (t) = 2 minutes = 2 * 60 = 120 seconds Charge (Q) = I * t = 2.5 A * 120 s = 300 C
