Correct Answer - Option 1 : current

Electric current:

An electrical phenomenon is caused by the flow of free electrons from one atom to another.

Electric current is the movement of free electrons predominately in one direction.

Electric current is expressed by the amount of charge flowing through a particular area in unit time. In other words, it is the rate of flow of electric charges.

In circuits using metallic wires, electrons constitute the flow of charges. However, electrons were not known at the time when the phenomenon of electricity was first observed. So, electric current was considered to be the flow of positive charges and the direction of flow of positive charges was taken to be the direction of electric current.

Conventionally, in an electric circuit, the direction of the electric current is taken as opposite to the direction of the flow of electrons, which are negative charges.
