Question

A block of pure silicon at $$300$$ K has a length $$0$$ . t m and area of $$1$$⋅$$0$$×$$10$$−$$4m2$$ if a battery of emf z y is connected across it, what is the electron current ? The mobility of electrons is $$0$$⋅$$14m2V$$−$$1s$$−$$1$$  and their number density is $$1$$⋅$$5$$×$$1016m$$−$$3$$

Infinity Learn · Accepted Answer

The electric field in block,$$E=V/lE=20$$⋅$$1=20V/m$$  and $$Ie=neAeve$$ $$=1$$⋅$$5$$×$$10161$$⋅$$0$$×$$10$$−$$41$$⋅$$6$$×$$10$$−$$19(2$$⋅$$8)$$ $$=6$$⋅$$72$$×$$10$$−$$7A$$
