What is the definition of mobility in the context of drift velocity and electric field?
Understand the Problem
The question is asking for the definition of mobility as it relates to drift velocity and electric field. Mobility is a measure of how quickly charge carriers can move through a material when subjected to an electric field.
Answer
Mobility is the drift velocity per unit electric field, indicating ease of movement through a material.
Mobility is defined as the drift velocity per unit electric field. It measures how easily a charge carrier, such as an electron, can move through a material when subjected to an electric field.
Answer for screen readers
Mobility is defined as the drift velocity per unit electric field. It measures how easily a charge carrier, such as an electron, can move through a material when subjected to an electric field.
More Information
Mobility is a key factor in determining how effectively an electric field can cause charge carriers to move, affecting the conductivity of the material.
Tips
A common mistake is confusing mobility with conductivity, though both are related, they are not identical. Mobility specifically refers to the ease of motion under an electric field.
