How do electrical charges flow?

Answer 1

The electrical charge that moves through a wire is in the form of negatively charged electrons. The movement of electrons in a circuit is called current. Electrons in a current are repelled from the negative end of the circuit and attracted to the positive end of the circuit.

Answer 2

Electrons move along a wire by hopping from one atom of a conducting element to the next atom - and so on, over and over - but they can only do this if there is an electric field acting across the wire.

For electrons to be able to move along any wire, the wire must be made of an element which is an electrical conductor.

Many elements can conduct electricity. Copper is one element which is a very good conductor. Silver and gold are also very good conductors. Iron is a conductor but is not as good at conducting electricity as copper, silver or gold.

Electrons can only move along a wire under the influence of an electric field.

The electric field is created by putting an electromotive force across the wire.

An electromotive force is measured in volts (also known as "a voltage") and can be produced by a chemical battery or by a machine called a generator.

Answer 3

Positive charges flow from a region of a high potential to a region of low potential whereas negative charges flow from a region of low potential to a region of high potential. This is because charges flow in a direction such that its potential energy decreases.

Answer 4

Electrical charges flow through a conductor when there is a potential difference (voltage) applied across it. The flow of charges is from an area of high potential (positive) to an area of low potential (negative), known as electron flow. In metals, the flow of charges is mainly due to the movement of electrons.

Answer 5

Current travels by the electrons. Example ( A Classic) When you have a potato and a zinc electrode and copper anode the electrons move from the copper to the zinc creating current.

Answer 6

Magnets move the electrons back and forth a tiny amount (50hertz /60hertz second) that tiny movement creates a current in the wire and you get your tv, radio ect to work.

Answer 7

Because of the flow of connectivity, this needs to occur in order for electricity to be generated.
