Drift velocity refers to the average velocity of charge carriers, such as electrons, in a conductor when subjected to an electric field. It represents the overall movement of these charge carriers through the material due to the applied voltage, rather than the displacement of individual electrons.

What do you mean by drift velocity and mobility of a free electron?
Drift velocity refers to the average velocity of free electrons as they move in response to an electric field. Mobility of a free electron is a measure of how easily an electron can move through a material under the influence of an electric field, and it is calculated as the ratio of drift velocity to the applied electric field.
What is velocity modulation in klystron?
Velocity modulation in a klystron refers to the process by which the velocity of the electron beam is varied to induce bunching of the electrons. This bunching enhances the interaction between the electrons and the RF signal in the cavities of the klystron, resulting in amplification of the signal.
If displacement is not changing as a function of time then what can we say about velocity?
If displacement is not changing as a function of time, then velocity is zero. Velocity is the rate of change of displacement with respect to time, so if there is no change in displacement, the velocity is zero.
How do you find displacement from velocity and time?
Displacement can be found by multiplying the velocity by time. If the velocity is constant, displacement can also be calculated using the formula: displacement = velocity x time. Remember to include the direction of the velocity in your answer.
How do you you find displacement from velocity?
To find displacement from velocity, you need to integrate the velocity function over the desired time interval. If the velocity function is changing, you can use calculus to find the area under the velocity-time graph to determine the displacement. Alternatively, you can calculate displacement by multiplying average velocity by time elapsed.

Does drift velocity of electron depend on diameter of conductor?
No, the drift velocity of electrons in a conductor does not depend on the diameter of the conductor. It is primarily influenced by the electric field applied across the conductor and the mobility of charge carriers within the material. The diameter of the conductor typically affects the resistance of the material, but not the drift velocity of electrons.

What is efffect on drift velocity by increasing the potential difference?
Drift velocity increases.

Alternatively, you can calculate displacement by multiplying average velocity by time elapsed.
Is displacement the change in velocity of an object?
Velocity is change in displacement over time.
Why drift velocity increases on increasing temperature?
Increasing the temperature excites more charge carriers in a conductor, causing them to move faster. This results in an increased drift velocity as the charged particles collide more frequently with lattice ions in the conductor, leading to a higher average velocity in a given direction.
How do you find displacement when you only have acceleration initial velocity and final velocity?
You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
What information do you need to calculate velocity?
To calculate velocity, you need the displacement of an object (the change in position) and the time it took to make that displacement. Velocity is determined by dividing the displacement by the time taken to achieve that displacement.
How does the velocity change if the displacement is halved but the time is unchanged?
If the displacement is halved but the time is unchanged, the velocity will also be halved. This is based on the formula: velocity = displacement / time. If displacement decreases by half but time remains the same, velocity will decrease proportionally.
