when the circuit is closed i.e. there is complete connection between all devices, there is an attraction for the electrons from the negative terminal towards the positive terminal. the flow/movement of electrons is called electric current.
A material that readily allows an electric current to flow is called a conductor. Conductors have low resistance and allow electrons to move freely. Examples include metals like copper and aluminum.
Electrical current cannot pass through materials that are insulators, such as rubber, glass, plastic, and wood. These materials do not allow the flow of electrons due to their high resistance to electric current.

Electricity is produced by the movement of electrons. When electrons flow through a conductor, such as a wire, it creates an electrical current that can be harnessed to power electrical devices.
by switching off the electrial items in the absence of any person
there will be no internet and things that are made of electrial would not work.
A Counter-current flow has more advantages as comapared to a co-current flow.
Electrical paths will always flow from a point of higher voltage to a point of lower voltage, following the path of least resistance. This flow of electricity occurs due to the movement of electrons in the circuit.
A current flow restrictor is a diode.
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
