When electric field is applied to the electrons in a conductor it starts
Updated On: Sep 24, 2024
- When electric field is applied to the electrons in a conductor it starts
- Drifting from higher potential to lower potential
- Drifting from lower potential to higher potential
- Moving with constant velocity
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The correct option is (C): Drifting from lower potential to higher potential
the electron starts drifting from the lower potential to higher potential.
drift velocity = \(v_d=-\frac{eE}{m}\tau\)

Concepts Used:
Electric Field
Electric Field is the electric force experienced by a unit charge.
The electric force is calculated using the coulomb's law, whose formula is:
\(F=k\dfrac{|q_{1}q_{2}|}{r^{2}}\)
While substituting q2 as 1, electric field becomes:
\(E=k\dfrac{|q_{1}|}{r^{2}}\)
SI unit of Electric Field is V/m (Volt per meter).
