Why does the resistance of conductor rise with temperature?
As temperature increases, the atoms in the conductor vibrate more vigorously, leading to more frequent collisions with free electrons. These collisions impede the flow of electrons, increasing resistance in the conductor.
What is the effect of temperature on drift velocity?
As temperature increases, the drift velocity of charge carriers in a material typically increases. This is because higher temperatures lead to greater thermal energy, which causes the charge carriers to move with higher average speeds. However, at extremely high temperatures, the increased thermal energy can also disrupt the regular lattice structure, leading to increased scattering and a decrease in drift velocity.
What is the effect on the drift velocity of free electrons by decreasing the length and the temperature of wire?
As we know , resistance(R) is directly proportional to length(L) of conductor and resistence(R) is inversely proportional to current (I) and I=nAqv (v is drift velocity) So , if we decrease the length of the conductor , resistance of the conductor will decrease and current(I) will increase and drift velocity of free electrons will increase . And as we know resistance and temperature have direct relation so , by decreasing the temperature resistence will decrease and current will increase . So drift velocity will increase .
Why drift velocity increase by increasing potential difference?
Increasing the potential difference across a conductor results in a higher electric field, which exerts a stronger force on the charge carriers (electrons). This causes the electrons to accelerate at a faster rate, increasing their average drift velocity through the conductor.
What relation between electric current and drift velocity?
The drift velocity of free electrons in a conductor is directly proportional to the magnitude of the electric current flowing through the conductor. This means that as the current increases, the drift velocity of the electrons also increases. The relationship is described by the equation I = nAvq, where I is the current, n is the number density of charge carriers, A is the cross-sectional area of the conductor, v is the drift velocity, and q is the charge of the charge carrier.

Why the magnitude of drift velocity is so small?
The magnitude of drift velocity is small because it represents the average velocity of charge carriers in a material experiencing an electric field. The individual charge carriers move at high speeds, but they collide frequently with atoms in the material, leading to a net low average velocity. The drift velocity is proportional to the strength of the electric field and inversely proportional to the charge carrier's mobility and the charge density.
WHAT is the order of drift velocity?
The order of drift velocity in conductors is typically on the order of micrometers per second. Drift velocity is the average velocity of charged particles as they move in response to an electric field within a conductor. It is influenced by factors such as the material's resistivity and the magnitude of the electric field applied.
What will be the direction of drift velocity in an electric field?
east
Define drift velocity?
Drift velocity is the average velocity with which charged particles, such as electrons, move in a conductor in the presence of an electric field. It is a very slow velocity due to frequent collisions with atoms in the material. Drift velocity is responsible for the flow of electric current in a circuit.
Drift velocity in two-phase flow?
it is the relative velocity of two phase that is gas and liquid.
What are Drift velocity and momentum relaxation time?
Drift velocity refers to a particle's average velocity being influenced by its electric field. Momentum relaxation time is the time required for the inertial momentum of a particle to become negligible.
