Question

Kindly explain drift of electrons equations

Answer 1

Dear Student
The free electrons move in random speed in a random direction. The movement of the electron occurs with net velocity and it is towards the high potential side causing drift velocity. This electron only flows towards the respective electrode and generate electricity.
Electron mobility is how quickly the electron move in a conductor
$$\begin{gathered} \mu =\frac{v_d}{E} \\ {v}_d=\frac{I}{nAq} \\ REGARDS \end{gathered}$$
