When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added.
When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.

differentialdiff means diffrentiate
d/dx sinx = cosx
In semiconductor two charge carriers are present i.e holes and electrons.The current is rate of flow of charges.so in ptype semiconductor the current is the sum of current due to holes and electrons.But current due to holes is more compsred to electrons in ptype.
they diffrentiate
since n type semiconductors have high mobility for electrons, they are preffered over ptype
Audio conferencing is just sound. Videoconferencing adds live video or motion pictures.
old concept emphasis was on its profits while newer one see public benefits too
white and red both do the work but mostly the red blood cells because they carry oxygen

long bones in our body are the resorviour of red blood cells. There from bone marrow stem cells the red blood cells diffrentiate
Goal Difference is an important statistic used in football, mainly to diffrentiate between 2 similarly placed teams. Goal Difference = Goals Scored - Goals Conceded.
