The electric current intensity (I) is the amount of electricity or electric charge (Q) that circulates through a circuit in the unit of time (t). Mathematically it can be described as

Our values are,


Replacing we have that the charge is


Therefore the amount of electric charge transported is 0.2137 Coulombs
