What will happen to the drift velocity of electrons in a conductor if a its length is increased b its temperature is increased?
As the temperature increases, the thermal agitation of the electrons increases thereby, increasing the number of collisions. Hence, drift velocity of the electrons decreases.
What is the change in the drift velocity of electrons if the voltage is doubled?
the drift velocity of electrons would reduce to half of it’s initial value when the length of the wire is doubled.
How is drift velocity related to length?
In simple terms, drift velocity is proportional to electric field intensity, which is V/d. When length d is doubled, field intensity becomes half, so drift velocity becomes half.
What happens to drift velocity of electrons when diameter is doubled?
If diameter of a conductor is doubled , then drift velocity of electrons inside it will not change. Although we have the relation I = neaVd.
What happens to the drift velocity of electrons in a conductor if its length is increased keeping other things constant?
If the length of the conductor is doubled, the drift velocity will become half of the original value (keeping potential difference unchanged).
What happens to drift velocity when length is halved?
And when the length of the conductor is halved l becomes l/2. Thus we find that when the value for potential difference of the conductor is doubled and the length of the conductor is halved then the drift velocity increases by four times.
Is drift velocity inversely proportional to length?
At constant potential difference, drift velocity is inversely proportional to the length of the conductor.
What happens to the drift velocity of electrons if the length of the conductor is doubled and the same potential difference is applied?
What happens to drift velocity when area is doubled?
The relation for drift velocity i=neυdA From it when current is constant Aυd is constant when radius is doubled, area becomes four times. Hence the drift velocity become one fourth (14) .
What happens to drift velocity if radius is doubled?
How does drift velocity change with diameter?
Drift velocity is independent of the diameter or cross-sectional area of the conductor. For the same p.d. V across the conductor, increase of cross-sectional area decreases the resistance R = (rho)(length)/(cross-sectional area) and thus increases the current (I = V/R).
