How moving electrons of space is being deflected by an electric field?
When an electric field is applied to moving electrons in space, the field exerts a force on the electrons due to their charge. This force causes the electrons to deviate from their original path and change direction. The amount of deflection depends on the strength of the electric field and the velocity of the 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.
Does an electric field exert a force on a beam of moving electrons?
Yes, an electric field exerts a force on a beam of moving electrons. The force exerted on the electrons by the electric field causes them to accelerate in the direction of the field. This acceleration can be measured and explained using Coulomb's law and the equation for the force on a charged particle in an electric field.
How does electricity travel through wires?
Electricity travels through wires by flowing as a stream of charged particles called electrons. When a voltage is applied to the wire, the electrons move in response to the electric field created by the voltage, creating an electric current that flows through the wire. This flow of electrons is what powers electrical devices and systems.
Why do electrons behave like tiny magnets?
Electrons behave like tiny magnets because they have a property known as spin. This spin generates a magnetic field around the electron, giving it magnetic properties. When electrons are in motion, their spin causes them to act like small magnets, aligning with an external magnetic field.
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 is the effect of electric field on cathode rays?
A cathode ray is nothing but a stream of negatively charged electrons. If electrons are moving through an electric or a magnetic field, they will be deflected.In the case of an electric field, the cathode ray would be deflected toward a positive plate and/or away from a negative plate. This follows the fundamental principle of electrostatics wherein opposite charges attract and like charges repel. In the case of a magnetic field, we have to apply Fleming's left hand rule to know about the direction of deflection of cathode ray. Note that the electrons must move across the magnetic lines of force, and not along them for the field to act on the moving charges and deflect them.
How are free electrons impelled along a conductor?
Free electrons in a conductor are impelled by an electric field created when a voltage is applied across the conductor. This electric field exerts a force on the free electrons, causing them to drift in the direction opposite to the electric field. As the electrons move, they collide with lattice ions, which impedes their flow, resulting in resistance. The overall movement of these electrons constitutes an electric current.

What is the force that causes electrons to move in a conductor?
The force that causes electrons to move in a conductor is an electric field created by a voltage difference across the conductor. This electric field exerts a force on the negatively charged electrons, causing them to flow in the direction of the electric field.
When electrons are rearranged in an object by an electric field the object is charged by what?
When electrons are rearranged in an object by an electric field, the object is charged by gaining or losing electrons. If an object gains electrons, it becomes negatively charged, and if it loses electrons, it becomes positively charged.
Can moving electrons through a magnetic field can produce an electric current?
Yes, a moving electron in a magnetic field can induce an electric current. This is the principle behind electromagnetic induction, where a changing magnetic field induces an electric current in a conductor.
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.
