Final answer:
To calculate the charge flow through the motor, multiply the current (0.3 A) by the time in seconds (180 s), resulting in a charge flow of 54 coulombs.
Step-by-step explanation:
The question asks how many coulombs of charge flow through an electric motor when a current of 0.3 A passes through it for 3 minutes. To find the charge flow (Q), we use the formula Q = I x t, where I is the current in amperes and t is the time in seconds. Since the question provides time in minutes, we first convert 3 minutes to seconds (3 min = 180 seconds).
Then we calculate the charge flow:
Q = 0.3 A x 180 s
Q = 54 coulombs
Therefore, a total of 54 coulombs of charge flow through the electric motor during the 3 minute period.
