The term for the flow of electrons through a circuit is?
electric current
How fast an electric current flow in a circuit?
the ability if a substance to slow down electric current
What enables the electric current to move through a material?
The electric current moves in the direction opposite to the flow of electrons by convention.When a potential difference is applied to a material which has "loose" electrons, the electrons move in a direction opposite to the potential gradient and the current moves in the opposite direction to the flow of electrons.This is how current flows in materials.
Why does electric current flow into circuits?
It may not be correct to say that an electric current will "flow into" circuits. Electrons move in a circuit in response to an applied voltage. And these electrons are alread in the circuit and available to support current flow if a voltage is applied. It may be more correct to say that electrons leave the negative terminal of a voltage source, and electrons enter the positive terminal of that voltage source. The electrons in the circuit that are availble to support current flow will "shift over" to create the current flow. Remember that the phenomenon of current flow in a wire is the "shifting over" of electrons in the wire. It's not about electrons going into one end of a wire and those same electrons coming out the other end. Use the link to the related question for more information that might help make things clearer.
Why do electrons change direction as they flow in a circuit?
Free electrons are in a constant state of chaotic movement in all directions. Under the influence of an external electric field, the continue to move in all directions, but there is a bias in one direction. So when we describe an electric current, the movement of individual electrons along a conductor is V-E-R-Y slow. So slow, in fact, that an individual electron is unlikely to pass through the filament of a flashlight before its battery has expired!
In a circuit electric current is flow of?
It is a flow of electrons.
What flows through a circuit and causes a magnetic field?
An electric current flowing through a circuit causes a magnetic field. This is due to the movement of electric charges, usually electrons, in the circuit. The magnetic field produced is perpendicular to the direction of the current flow.
Why can't an electric current exist if the circuit is broken?
If the electric circuit is broken, there will be no medium for transfer of electrons and flow of current. Hence, electric current does not exist.
What is the electrical current in a circuit?
Conventionally electric current was assumed to be a flow of positive charges. But in reality especially in metals electric current is due to the flow of negatively charged electrons. So direction of conventional current is opposite to the direction of flow of electrons. But in case of liquids as well as solids electric current is due the flow of both positive and negative ions.
What must occur before the current flows through a circuit?
As current is the rate of flow of electric chargesAs I=Q/tso,there must be free electrons for the flow of electric current in a circuit.Then when voltage is applied at the terminals of circuit the free electrons acquire an average velocity called as drift velocity in the opposite direction to that of electric field (-E).Now the free electrons modify there random motion and a steady current begin to flow in a circuit.
The term for the flow of electrons through a circuit is?
electric current
Is somthing that flows through an electric circuit an eletrical current?
Yes. Current consists of electrons flowing in a circuit.
When electrons are moving from negative pole to positive pole in the circuit then current in the circuit will be moving in which direction?
always current flow from the opposite direction of electron
How fast an electric current flow in a circuit?
the ability if a substance to slow down electric current
Electric current in which electrons repeatedly change direction?
AC
Do protons travel through an electric circuit at or near the speed of light?
Electricity, this may be electrons in a direct current. In an alternating current the electrons stay where they are and it is only the energy that moves between electrons.
What is an alternating circuit?
an electric current that changes it direction or strength repeatedly
