Current. The flow of electrons is the flow of a moving charge. The rate of flow is current (the amount of charge that flows in a set time). The equation is: I = Qt Hope this helps.
Heat & pressure.
Current flow or the change of charge in time.
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.
The direction of the flow of electric current. In a positive object, electrons flow to it because it has an abscence of negative charge (aka electrons). In a negative object, it has an abundance of negative charge (electrons) so electrons flow away from it.
For example, you can make an analogy with the flow of water in a tube.
A difference in charge
A device to get a current flow through a wire (i.e. from a battery) and no breaks in the wire.
By the application of a voltage source electric charge will flow.
A difference in temperature
negative pressure is needed for a sustained flow of water in a pipe.
negative pressure is needed for a sustained flow of water in a pipe.
Potential Difference
The only two things needed for current flow are electromotive force or voltage and a conductor. The amount of current flow will depend on the "Resistance" in the circuit.
flow of charge is called current. but the direction of flow of current is always taken oppsite to the flow of charge.
An electrical charge is the result of the flow of electrons.
yes charge flow through the circuit
