Correct Answer - Option 1 : 2 A

Concept:

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)

$I=\frac{Q}{t}$

Calculation:

Given that:

Charge(q) = 40 Coulomb.

Time(t) = 20 seconds.

By using the formula:

$I=\frac{40}{20}$

I = 2 Ampere.
