Correct Answer - Option 1 : 2 A
Electric Current: It is defined as the net amount of electric charge (q) flows through a cross-section of a conductor in an electric circuit in a per unit time (t).
The SI unit of electric current is Ampere(A).
Electric current (I) = Electric charge (q)/Time (t)
Charge(q) = 40 Coulomb.
Time(t) = 20 seconds.
By using the formula:
I = 2 Ampere.
