What makes an electric current?
An electric current is the movement of the conduction band electron "gas" in a conductor. This can be induced in various ways:Application of a voltage difference across the conductor.Having magnetic flux lines "cut through" the conductor, which will push the electron "gas" perpendicular to the plane the flux lines "cut".Connecting the conductor to 2 dissimilar metals and placing the metals in an electrolyte. Corrosion of one of the metals will cause current in the conductor.etc.
What is the formula of electric current?
the formula for electric current is VI ,where v is voltage then I is the current. the unit used for current is ampere and volts for voltage. multiply the total I to the Voltage The formular of electric current is given by I=V/R ,I=P/V
How fast an electric current flow in a circuit?
the ability if a substance to slow down electric current
Why emitter current flows away from base in NPN transistor?
arrows are shown for conventional current, not electron current.
How can you make an electric current stronger?
An electric current through a resistive circuit can be increased by decreasing the resistive load or increasing the voltage of the circuit.
Explain with the help of diagram how free electrons and hole contribute to electric current?
In a semiconductor material, free electrons and holes can conduct electricity. Free electrons are negatively charged particles that move in response to an electric field, creating an electron flow or current. Holes are spaces within the crystal lattice where an electron is missing, and they behave as positively charged carriers that can also move in response to an electric field, contributing to the overall current flow. Both free electrons and holes play a role in conducting electricity in semiconductors.
What subatomic particle is responsible for producing electric current?
The electron.
What is the charge of the particle that results in an electric current?
Negative. (the electron)
What is the ability of light to cause electron movement and electric current?
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
What is the unit of electron current?
Electron current flow is measured in coulombs per second, which is known as amperes. A coulomb is about 6.242 × 1018 electrons.
Is it true that when an electric current flows through a long conductor each free electron moves through a relatively short distance?
It is not true that when electric current flows through a long conductor each electron moves through a relative short distance because electric current is the continues flow of electrons.
What is electron movement referred to as?
Electron movement is referred to as electric current. When electrons flow through a conductor, such as a wire, they carry electrical energy from one point to another. The direction of current flow is opposite to the direction of electron movement.
Why electric current cannot exist if an electric circuit is broken?
Current flow is fully based on motion of electrons since there is no possibilities to motion electron in open circuit there no current flow.
Is current a flow of electrons?
In general, yes, we normally think of the movement of electrons (electron flow) as electric current.
Why is electric current?
in pure physics language flow of electron is called current and applied languges is refered as electrisity
What is it called when you measure of how much electrical energy carries electrons?
Electron flow is current, or coulombs per second. Electron potential is voltage or joules per second.
What is electric current flow?
Answerits lightning, for a more simple answer......electric current flow is the movement of charges. Most often, however, we consider electric current flow to be moving electrons, or electron current flow.We most often use the term electric current flow to refer to the moving electrons, the flow of which is measured in amperes.Earlier scientists, before the discovery of electron, do believe that current flows right from positive terminal to the negative. This is known as conventional current flow.So electron flow is always opposite the direction of conventional current.
