What is the condition that is necessary for a charge to move in a wire?
The necessary condition for a charge to move in a wire is the presence of an electric field, which exerts a force on the charge causing it to move. This movement of charges in a wire is what constitutes an electric current.
Is a current-carrying wire electrically charged because of the electrons moving in it?
A current-carrying wire is not electrically charged because of the movement of electrons. The wire as a whole remains electrically neutral even though the electrons are moving within it. The flow of electrons is what constitutes an electric current.
What is a flow of electrons moving along a wire or conductor?
An electric current. <<>> The term used for the flow of electrons through a conductor is amperage.
What are 3 ways to induce an electric current in a wire?
You can induce an electric current in a wire by moving a magnet near the wire, passing a current through a nearby wire, or changing the magnetic field around the wire.
Why does a wire carrying electric current become hot?
A wire carrying electric current becomes hot due to the resistance in the wire. As the electric current flows through the wire, the resistance causes some of the electrical energy to be converted into heat energy, which raises the temperature of the wire.

What happens when electric current is passed through Cu wire?
When electric current is passed through a copper (Cu) wire, the free electrons in the wire start to move in the direction of the current flow. This movement of electrons constitutes an electric current, which generates heat due to resistance in the wire. The wire may also produce a magnetic field around it as the electrons move.
Is a current-carrying wire electrically charged because of the electrons moving in it?

Which particle constitutes the electric current in a metallic conductor?
electrons

Electric current in a metal conductor is carried by?
Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.
Why does a wire carrying electric current become hot?
A wire carrying electric current becomes hot due to the resistance in the wire. As the electric current flows through the wire, the resistance causes some of the electrical energy to be converted into heat energy, which raises the temperature of the wire.
Why electric current across a wire drops?
Electric current does not drop. Electric voltage, however, drops across a wire because the wire has non-zero resistance. (Do not confuse electric current with electric voltage - they are not the same.)The reason current does not drop is that, in a series circuit, according to Kirchoff's current law, the current at every point in a series circuit is the same.
What is the relationship between the speed of electrons in a wire and the flow of electric current?
The speed of electrons in a wire is typically very slow, but the flow of electric current is fast. This is because when a voltage is applied to a wire, it creates an electric field that pushes electrons along the wire, causing the flow of electric current.
Why does the current flow through wire?
Current flows through a wire when there is a difference in electric potential between two points. This potential difference creates an electric field that drives the flow of electric charge (current) through the wire.
Can a magnet stop an electric current?
A magnet cannot stop an electric current, but it can influence the flow of the current. Moving a magnet near a wire carrying an electric current can induce a voltage in the wire, which can affect the behavior of the current.
