Answer:1440 coulombs.
Explanation:The formula to calculate the amount of charge that flows through a circuit is:
Charge (Q) = Current (I) x Time (t)
Given that the current flowing through the element of the electric iron is 0.4 amps and the time is 1 hour, we can calculate the amount of charge that flows through the circuit as follows:
Q = I x t
Q = 0.4 A x 3600 s
Q = 1440 C
Therefore, the amount of charge that would flow in one hour through the element of an electric iron drawing a current of 0.4 amps is 1440 coulombs.
