Explain Mobility.
Average drift velocity of electrons (e-) in an applied field is proportional to the field, the absolute magnitude of the proportionality factor eq/m, termed like the mobility of the electrons that is denoted by µ. Therefore the mobility may be defined with the magnitude of the average drift velocity per unit field.
The mobility of the electrons can be found by identifying the conductivity of the material and calculating the number of free electrons. Unit of mobility is m²/volt.sec
