transfer/movement of electrons
What else can I help you with?
What movement results in a electric current?
Movement of electric charges through a conductor results in an electric current. This can occur when electrons flow through a wire in a circuit, creating a continuous flow of charge.
What opposing force must be overcome by charges blowing in electric current?
Resistance is the opposing force that must be overcome by charges blowing in an electric current. Resistance is caused by factors like the material of the conductive medium, its temperature, and the dimensions of the conductor.
What must be present for an electric current to flow?
For an electric current to flow, there must be a closed circuit allowing the movement of charged particles (typically electrons) from a high potential to a low potential. Additionally, there must be a potential difference (voltage) between two points in the circuit to drive the flow of electricity.
What is the opposite of a electric current?
The opposite of an electric current is the absence of an electric current, meaning no flow of electric charge through a conductor.
In which case will electric current be induced in a coil of wire?
An electric current will be induced in a coil of wire when there is a change in magnetic field passing through the coil, according to Faraday's law of electromagnetic induction. This can occur when the magnetic field is moving relative to the coil or when there is a change in the strength of the magnetic field.
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.
What most occur to produce electric current?
Chemical changes, change in magnetic flux linked with a conductor cause the production of electric current.
What must occur to produce electric currents?
transfer/movement of electrons
What movement results in a electric current?
Movement of electric charges through a conductor results in an electric current. This can occur when electrons flow through a wire in a circuit, creating a continuous flow of charge.
What is the best electric current?
This depends upon the application. For most home appliances and industrial machinery, alternating current is the best electric current. In most computer electronics, alternating current must be converted into direct current.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
What opposing force must be overcome by charge flowing electric current?
Resistance
How can electric current change?
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
In order to conduct an electric current a substance must contain a what?
It should contain some IONS, or charged particles.
What makes an electric cuchi?
An electric current relies on several things. First, there must be a continuous connection of conductors. Then there must be a voltage or a potential difference between two parts of a circuit. It is the voltage that causes electrons to move, so generating an electric current. The amount of current depends on both the voltage and the resistance of the circuit. The higher the voltage, the greater the current. The higher the resistance, the lower the current will be.
What opposing force must be overcome by charges blowing in electric current?
Resistance is the opposing force that must be overcome by charges blowing in an electric current. Resistance is caused by factors like the material of the conductive medium, its temperature, and the dimensions of the conductor.
If a material conducts electricity easily what will it have?
It must have a low resistance to the flow of electric current.
