reverse bias doesnt allow passage of current..den how cum reverse bias in de base collecter diode in a n-p-n trasister gives a large amount of current..how cum???

here although the base collector region is in reverse bias,5% of the electrons entering p region, from emitter recombines with holes there. 95% of the electrons attracted by strong reverse bias potential at the collector end gives rise to high collector current.
