It means that due to the temperature, electrons move back and forth randomly, even if there is no current. A current would imply a systematic movement of electrons, i.e., more electrons moving in one direction than in the other.
The electron thermal velocity is important in plasma physics because it determines how fast electrons move due to their temperature. This velocity affects various plasma phenomena, such as energy transfer and wave propagation, making it a key parameter in understanding and analyzing plasma behavior.
Thermal velocity can be defined as the speed at which particles move to make up a gas, liquid, or other such substance. Thermal velocity is a measurement of temperature. This is a common term used in medicine research.
The thermal speed of electrons in a conductor is typically on the order of 1,000,000 m/s. This speed represents the average velocity of electrons due to their thermal energy at a given temperature. It is important to note that individual electron velocities can vary widely within the conductor.
The velocity of an electron in the photoelectric effect is primarily determined by the energy of the incident photon. If the photon energy is greater than the work function of the material, the electron can be ejected with higher velocity. Additionally, factors like the electric field in the material can influence the electron's velocity.
No, the momentum of an electron can change depending on its velocity and direction of motion. Momentum is a vector quantity that is the product of an object's mass and velocity. So if the velocity of an electron changes, its momentum will also change.

Thermal velocity occurs in situations where particles have random kinetic energy due to their temperature. This can happen in gases, liquids, or solids when the particles are vibrating or moving randomly. Thermal velocity is a measure of the average speed of the particles in a substance due to their thermal energy.
The velocity experienced by an electron in an electric field depends on the strength of the field and the mass of the electron. The velocity will increase as the electric field strength increases. The electron will accelerate in the direction of the electric field.
Velocity is a speed in a very specific direction.
The direction of the magnetic force on an electron is perpendicular to both the electron's velocity and the magnetic field it is in.
The formula used to calculate the speed of electrons in a given system is v e/m, where v represents the velocity of the electron, e is the charge of the electron, and m is the mass of the electron.
formation of thermal energy
An electron can reach zero velocity by experiencing a slowing force, such as friction, that opposes its motion. Alternatively, if an equal and opposite force acts on the electron to stop its movement, it can also reach zero velocity.
