The definition of a current is a collection of moving charges.
Hence for current to flow, one needs charge and one needs it to move.
One gnerally aciees this on Earth with a conductor and a voltage or potential difference that creates and electric field and charges feel a frorce and move creating current.
The conductor may be a wire and the charges may be electrons.
The conductor might also be water with dissolved salt and the electric field causes the salt ions to move and it is the moving ions that constitute the current.
If you are the Sun and you are producing electrons and protons on the solar wind, then complex electromagnetic fields may have ejected the charges from the sun, but the current that is the charge moving through space is maintained just hy the inertial of the particles. You don't need an electric field to maintain the current and you don't need a conductor to hold the charges.
For a current to flow, you need net charge moving. That is all. Current is technically charge density times velocity.

What equipment is needed for testing electrical current?
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
What does an electrical current flow in?
Electrical conductors.
What does a load do to the flow of electrical current in a series circuit?
A load increases the flow of electrical current in a series circuit. No load, no flow.
Difference between electrical current and electrical charge?
current is the flow of charge.
Th flow of an electrical current be?
The flow of an electrical current be -- Coulombs per Second or Ampere hours per hour.
What causes a current in an electrical current?
Electrons flow because of electrical attraction and repulsion.
A flow of electrical charges is known as an?
A flow of electrical charges running through a medium is known as an electrical current.
In automotive electrical circuits current is considered to flow from?
In automotive, electrical circuits current is considered to flow from the battery. Most cars will have a 12-volt battery which will provide the electrical circuits current.
What is the name for the flow of electrons in an electric circuit?
A flow of electrons in an electrical circuit is called a current, which is the name given to the amount of electrical charge flowing in a certain period of time.Any total quantity of electrical charge is measured in coulombs.Any flow of electrical current is measured in amps.1 amp is equal to a flow of 1 coulomb of electrical charge in one second of time.
What is a current in electricity?
The flow of electrons is called an electrical current.
What is and electrical current?
current electricity is where electrons flow through a conductor.static electricity electrons do not flow
The flow of charged particles is an electric?
The flow of electricity is called electrical current.
