Answer:

The amount of electrons that flow in the given time is 3.0 C.

Step-by-step explanation:

An electric current is defined as the ratio of the quantity of charge flowing through a conductor to the time taken.

i.e I =
(Q)/(t) ...................(1)

It is measure in Amperes and can be measured in the laboratory by the use of an ammeter.

In the given question, I = 1.5A, t = 2s, find Q.

From equation 1,

Q = I × t

= 1.5 × 2

= 3.0 Coulombs

The amount of electrons that flow in the given time is 3.0 C.
