Answer
1200 C or 1.2 kC
Work Step by Step
The formula that connects Current, Time and Charge is
Q=${I}\times{t}$
where Q is charge in Coulomb (C), I is current in Amperes (A) and t is time in seconds (s).
According to the data provided in the question,
I=5 A
t=4 min which means 240 seconds
Q=?
Using the above mentioned formula,
Q=${5}\times{240}$
Q=1200 C
Transform to kilocoulomb by dividing the answer by 1000, Q=1.2 kC
