Answer = 0.05A
Using the equation Q=IT and rearranging it to find current to become I=Q/T, where:
Q = charge (Coulombs)
I = current (Amperes)
T = time (seconds)
Known values from the question:
Q = 475
T = 2.5 x 3600 (converting the 2.5 hours into seconds as this is the SI unit for time)
T = 9000
Substitute the known values into the equation:
I = Q/T
I = 475/9000
I = 0.05 (rounded to 1 s.f)
