when the conductor connected with electric source, then the current is flowing through a conducter.
hope it helpful

Answer 2

Answer:

We say that a current is flowing through a conductor whenever the circuit is connected to an electric source or charge is flowing through the conductor (metallic wire) .We can detect the presence of charge with the help of an ammeter.

Explanation: Current means rate of flow of charge and so, if charge flows through a conductor we can say that the current is flowing. The presence of current (charge, as flow of charge is called current)can be easily detected by using an ammeter.
