Electricity will flow if there is a conductor (a material that conducts electricity), and a voltage. The conductor should form a closed circuit. To have a more or less permanent voltage requires a source of energy, such as a battery, or a connection to household current.

∙ 13y agoElectric current flows through closed loops across which a voltage has been applied. For example, connecting the negative and positive terminals of a battery will cause current to flow. This is due to the chemical potentials of the respective terminals, which are a measure of their affinity for electrons. An interesting illustration of chemical potentials is the implementation of new battery technology.
The chemical potential is a defined number for any substance. The bigger the difference between two chemical potentials in a battery, the greater the voltage that can be generated. Regular batteries use Zinc and Copper ions in separate chambers to create the chemical potentials. Newer batteries use exotic materials like Lithium ions that can generate more electricity per unit mass and are rechargeable, but are a bit more expensive.

What actually moves when an electric current flow?
Electrons move in electron current flow.
What is a electron flow in only one direction called?
A current.
What is the conventional current flow?
Conventional current flow is the flow of positive charges, or the equivalent flow of positive charges. That is, if what flows is really negative charges (for example, an electron), which flow in one direction, the "conventional current" flows in the opposite direction.
Why the current flow from higher potential to lower potential?
Current defined as Positive charge flow , flows from higher potential to the lower. Current defined as electron flow, flows from lower potential to higher. In general Potential and Current are defined by positive charge.
Is an electric current a flow of charge?
Electrons are a negative charge. Using conventional notation current flows from positive to negative poles of a battery, for example. In electron flow convention the electrons flow from negative to positive.
Flow of an electron will contain how much current?
1.6x10^19 amperes is the amount of current that a flow of an electron will contain.
Electron current flow theory considers electricity to be the flow of charge carries which are what in polarity?
When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.
What actually moves when an electric current flow?
Electrons move in electron current flow.
Difference between electron flow and conventional current?
Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).
Which way does the current flow in a car?
The current flow is from positive to negative whereas electron flow is from negative to positive.
Where Electron current flow is from?
P to N
What is a unit of measuring rate of electron flow in a circuit called?
Electron flow is known as 'current' the unit of current is an amp
What is the direction of current due to flow of electrons if it is not conventional current?
Electron flow is from negative to positive. Conventional current flow is from positive to negative.
What flow is equal to and opposite of electron flow?
The "flow of current" is considered to be in the opposite direction.
Why it is that electron does not flow there is no current flowing?
Electrons are in random motion in a material, such that there is no resultant electron movement. Hence a material has no current flow by its own. Only the directed flow of this charge in a direction, will results in current. when we provide sufficient energy (for example by mean of applied potential difference ) the net motion of the electron gives rise to the current flow.
What electron flow is difficult between atoms?
valence band current flow.
What is an electron current?
the flow of electrons through a conductor
