The very word current means 'flow'. Electric current is the flow of electric charges. There are two kind of electric charges. Scientists considered the electric current as the flow of positive charges. But in case of solid metals, only negatively charged electrons are able to move freely where as the positively charged protons are held firmly within the core of the atoms. So electric current is due to negatively charged electrons. Now we have to differentiate these two. How? Let us consider the current due to flow of positive charges as conventional current flow. Hence conventional current direction is always opposite to the direction of flow of electrons. To keep the charges in motion we need a force to push them. So we use a chemical cell which has electrical potential difference between the two terminals. This potential difference is named as " electro motive force", in short "emf". So emf is responsible to make electric charges to flow.

When does electricity flow?
When there is a closed circuit, there is electricity flow.
Is voltage a flow of electricity?
no...current is a flow of electricity
How is the flow electricity of electricity mearsure?

How can electricity flow?
Electricity dose not truly "flow", it is the exchange of electrons.

switch...this break the flow of electricity, from a circuit
Did electricity flow through the wire when the circuit was opened?
Electricity does not flow in an open circut
What is the fundamental concept that describes electricity as the flow of protons?
Electricity is the flow of electrons, not protons.
What elements allow electricity to pass through?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.A circuit lets electricity flow through it.Conductors allow the easy flow of electrons. Conductors are metal, usually copper or aluminum.Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.Metals are good conductors. They provide little opposition (resistance) to the flow of currentNote that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons.A conductor lets electrons easily flow in it.
Something that will not let electricity flow through it?
Something that does not allow current to flow is called an insulator. "Electricity" doesn't flow, only current, which is one aspect of electricity, does. Note, current is the flow of electrons.
What is and electrical current?
current electricity is where electrons flow through a conductor.static electricity electrons do not flow
What is the term for an obstacle that impedes the flow of electricity?
The term for an obstacle that impedes the flow of electricity is "resistance."
