1 Answer

Answer :

: The conventional direction of electric current is taken from higher voltage to lower voltage or from the positive layer of the electric cell to the negative layer. But in fact the flow of electricity is due to the negative charge i.e. the flow of electrons , so the actual direction of the flow of electricity is from the lower voltage to the higher voltage i.e. from the negative plate of the electric cell to the positive plate.

(2) experience collision less frequently Explanation: When an electric field is applied, both the valence electrons and the free electrons move in the same direction. The hole direction is opposite to that of valence electron but the mobility is the same. Even for the same electric field, valence electrons cannot move as freely as the free electrons because its movement is restricted due to collisions. Therefore, the velocity of valence electrons is less compared to free electrons. In other words, the velocity of holes is less compared to free electrons. This means mobility is also less for a hole compared to free electron.
