Question:
Magnitude of drift velocity per unit electric field is known as:
Magnitude of drift velocity per unit electric field is known as:
Show Hint
Mobility is a critical parameter in semiconductor physics, indicating how quickly carriers (electrons or holes) can move through a semiconductor material under an electric field.
Updated On: Apr 7, 2026
- Displacement current
- Mobility
- Electric resistance
- Electrical conductivity
- Relaxation time
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Mobility is defined as the magnitude of drift velocity per unit electric field. It is expressed as:
\[
\mu = \frac{v_d}{E}
\]
where \(v_d\) is the drift velocity and \(E\) is the electric field strength.
