How does the flow of charge take place inside a wire?

The flow of charges in an electric wire is due to the potential difference provided by a cell/battery or other medium. Once the potential difference is provided, the electrons are provided the force which drives them through the wire. Hope it helps!

What happens when an excess charge is placed on the surface of a conducting body?

When excess charge is placed on a conductor or the conductor is put into a static electric field, charges in the conductor quickly respond to reach a steady state called electrostatic equilibrium. The free charges move until the field is perpendicular to the conductor’s surface.

Why does excess charge lie on the surface of a conductor?

The inside of a conductor cannot contain any net charge. Such charges would produce a field inside the conductor, and electrons would move and cancel out the field and neutralize the charge. Any excess charge on a conductor must therefore reside on the surface.

When a current flows in a circuit is there an electric field inside the conductor?

A conductor has free electrons. As long as electric field is not zero, the free charge carriers would experience force and drift. In the static situation, the free charges have so distributed themselves that the electric field is zero everywhere inside. Electrostatic field is zero inside a conductor.”

How electric charges flow inside a wire explain Class 10?

Whenever we apply potential difference across a wire an electric field is created in the wire. This electric field makes the free electron move in the direction opposite to the electric field (this happens because electron has negative charge, So it moves in opposite direction) with a speed called drift speed.

How the charge will flow answer?

Answer: In conductors where the charge carriers are positive, conventional current is in the same direction as the charge carriers. In other conductive materials, the electric current is due to the flow of both positively and negatively charged particles at the same time.

Why the charge inside a conductor is zero?

A conductor is a material that has a large number of free electrons available for the passage of current. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.

Why is there no charge inside a conductor?

The inside of the conductor does not contain any charge. If charges were present inside a conductor then such charges would produce an electric field and the electrons would move and cancel out the field neutralizing the charge.

Can a conductor have charge inside its surface?

In all conductors, charges reside on the surface. The reason for this is that conductors have free electrons, that is, the electrons are loosely attached to the nucleus of the atoms in the conductors.

Can current flow without electric field?

If there are no sources of electric current, such as battery, then the electrons in the conductor will redistribute until the electricfield in the conductor is reduced to zero, at which point these transient electric currents cease. Thus in static systems, the electric field inside conductors is zero.

Is there an electric field inside a wire?

Although a wire is a conductor, there is no electric field in it just because it is capable of conducting current! If you connect a battery to the ends of the wire, the battery voltage creates an electric field that, in deed, causes the electrons in the wire to move and try to “neutralize” the electric field.

What happens when electric current flows through a wire?

In fact, when electric current flows through a conductor, it generates a magnetic field around the conductor. The magnetism resulting from flowing electric charges is called electromagnetism. stronger magnetic field, you can wrap the coils around an iron rod (or other iron object).
