Step-by-step explanation:
The time it takes for a certain amount of charge to flow through a circuit is given by the formula t = Q/I, where t is the time, Q is the charge, and I is the current. Therefore, we can find the time it would take for 500C of charge to flow through a motor with a current of 2MA (2 milliamperes) using the following steps:
Q = 500C
I = 2MA = 0.002A
t = Q/I = 500C / 0.002A = 250000 seconds
Therefore, it would take 250000 seconds for 500C of charge to flow through the motor at a current of 2MA. This is equivalent to approximately 69.4 hours or 2.9 days.
