Final answer:
Current is the measure of the number of electrons flowing past a given point in 1 second. It is measured in amperes (A), where 1 A is equal to 1 C/s.
Step-by-step explanation:
The measure of the number of electrons flowing past a given point in 1 second is called current. Current is measured in units called amperes (A). It is defined as the rate of flow of charge, where 1 ampere is equal to 1 coulomb of charge passing through a point in 1 second.
For example, if 45 coulombs of charge move past a point in 1 second, the current in the circuit would be 45 amperes (A).
