Electrical conductors (wires) are primarily made of copper or aluminum. All metals will conduct current. Conductors are elements that have 1 or 2 electrons in the outer (valance) shell of their atoms. These electrons are loosely held or are already floating around in the crystalline lattice of the material. When a voltage is applied to a conductor, these electrons move from negative to positive, since electrons have a negative charge (like charges repel, unlike charges attract).

∙ 13y agoTo understand cause of electricity first we have to understand electricity.Electricity is due to flow of charge or electrons.
Now main cause of electricity is presence of free electron,this is in case of metal.In case of conducting solution the cause of electricity is the ions.

∙ 12y agoTo flow electricity or current through a conductor, the following points must be considered:
- Voltage or Electric potential must be applied to the circuit
- Circuit through which current flows must be closed
Wiki User
∙ 14y agoVery basically stated: an imbalance in electrons combined with the conductivity of metal, which is enough for electrons to shoot through. That's why electricity is usually through metal wires

∙ 9y agoElectricity needs a current in order to flow. The electrical current is a flow of electrons that maintains current and voltage.

What is a measure of force with which negative charges flow called?
The force that causes negative charges to flow is the electromagnetic force. And we often apply the term voltageto the force that causes electron current to flow in what we normally think of as electricity.
Something that will not let electricity flow through it is an?
Note that "electricity" doesn't flow, only current, which is one aspect of electricity, does. Current is the flow of electrons. Anything that doesn't allow current is an insulator
What does the resistance of the flow of electrons cause?
it cause no electricity because of the resistance but.... if your question was..... "the caused by the flow of electrons" then the answer well be ( it cause electricity )
Electricity is the device that control?
A: Electricity is not a device but rather a fiscal flow of electrons
What circuit does not allow electricity to flow through?
An open circuit.
What particle of an atom causes the flow of electricity?
electrons
In the photoelectric effect what happened when light hits the metal?
electrons are knocked off atoms causing electricity to flow
What does voltage cause the flow of?
there is a difference in electrical potential energy.
What is the main force in nature that causes water to flow?
Is it momentum friction electricity or gravity
How does a generators produce electricity?
. This causes electrons to move through the conductor, which is creates a flow of electricity that we can use for lighting or running our computers.
What is a measure of force with which negative charges flow called?
The force that causes negative charges to flow is the electromagnetic force. And we often apply the term voltageto the force that causes electron current to flow in what we normally think of as electricity.
What within a cell causes the charge that allows electricity to flow through wires?
Corrosion of the metal plates in the battery cells drive current 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?
flow of electricity is measured by an instrument galvanometer
What causes electricity to flow through the wire?
electro-motive force (emf), often measured in volts of "potential"
How does an insulator affect the flow of electricity?
It prevents the flow of electricity since they do not have mobile electrons or mobile ions to allow the flow of electricity.
