Electric current is sometimes incorrectly defined as simply a flow of electrons What is wrong with this definition?
Electric current is the rate of flow of electrons.
AnswerA more accurate definition of electric current would be that it is a flow of electric charges. While current flow in a metallic conductor is, indeed, a flow of electrons, in other conductors -such as electrolytes- current flow may be a movement of ions. So, it would be more accurate to define current in terms of charge flow, rather than in terms of electron flow.
What else can I help you with?
True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?
False. The imbalance of electrons in an atom does not create electric current. Electric current is the flow of electric charge, which is the movement of electrons through a conductor. The movement of electrons in an atom due to an imbalance is known as an electric field, which can lead to the flow of electric current when a conductor is present to allow the movement of electrons.
When an electric field is applied to a metallic crystal the movement of electrons is?
When an electric field is applied to a metallic crystal, the movement of electrons is towards the direction opposite to the field. This is because electrons are negatively charged particles and will experience a force in the opposite direction to the electric field. This movement of electrons constitutes an electric current.
What does a collection of free electrons in one place create?
A collection of free electrons in one place creates an electric charge. These free electrons can move under the influence of an electric field, leading to the flow of electric current.
Which form of energy is due to the movement of electrons?
Electric energy is due to the movement of electrons. When electrons flow through a conductor, they create an electric current that can be harnessed to power electrical devices.
Positive ions and electrons can flow in a a solution but only electrons can flow in wires. What causes the electrons to move?
In wires, the movement of electrons is driven by an electric field created by a voltage source. This electric field exerts a force on the electrons, causing them to move. In contrast, in a solution, positive ions and electrons can move because of the flow of electric current through the solution.
What is the definition for electric current?
Flow of electrons
What is the Definition of electric power and its formula?
The flow of electrons to create energy.
What is definition of electric current?
Current is the motion of electrons in a conductor being propelled by electromotive force (voltage).
What is the definition for positive charge?
having a deficiency of electrons ;having a higher electric potential
What is the definition of negative electric charge?
Negative electric charge is a fundamental property of subatomic particles, indicating an excess of electrons compared to protons. It is the opposite of positive electric charge and is responsible for the attraction between particles with opposite charges.
True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?
False. The imbalance of electrons in an atom does not create electric current. Electric current is the flow of electric charge, which is the movement of electrons through a conductor. The movement of electrons in an atom due to an imbalance is known as an electric field, which can lead to the flow of electric current when a conductor is present to allow the movement of electrons.
In which direction does the electric force act on electrons?
The electric force acts in the opposite direction of the electric field on electrons.
Do electrons create electric currents?
Yes, electrons carry electric current when they flow through a conductor such as a wire. The movement of electrons is what generates the flow of electric charge known as an electric current.
Which automatic practicles have a negative electric charge?
its electrons
What is the definition of electricity not what it means?
Electricity is a form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current. It is characterized by the flow of electric charge through a conductor.
What is electrons contribution to electricity?
Electrons carry electric charge. When they move through a conductor, they create an electric current, which is the flow of electric charge. This flow of electrons is what powers electrical devices and enables the transmission of electricity.
A shortage of electrons on a surface creates an electric what?
A shortage of electrons on a surface creates an electric charge imbalance or positive charge. This can lead to the attraction of electrons from neighboring surfaces to balance the charge and create an electric field.
