Questions
A block of pure silicon at 300 K has a length 0 . t m and area of if a battery of emf z y is connected across it, what is the electron current ? The mobility of electrons is and their number density is
detailed solution
Correct option is A
The electric field in block,E=V/lE=20⋅1=20V/m and Ie=neAeve =1⋅5×10161⋅0×10−41⋅6×10−19(2⋅8) =6⋅72×10−7ASimilar Questions
