Due to i/p current wcich is small, the electrons which are
less in no and are randomly moving in the transistor starts
moving with large speed. This causes collission and
produces more and more electrons. the new electrins also
takes part in this and due to large no. of electrons
comparatively large o/p current flows which is nothing but
amplification.
