Electric current is the flow of charged particles called blank .

The electric current is the flow of electrons which are negatively charged particles.

 Explanation:

The flow of electrons in a circuit is called the electric current. It is measured with one coulomb of charge across the circuit in 1 second that is called an ampere. This ampere is the standard unit of electric current.

The flow of electrons across the circuit is achieved by the potential difference across the circuit. This potential difference is the difference of electrical voltage generated across the circuit in order to achieve flow of current.

probably not if net force is zero

there are no atoms
