1. The electron and hole concentrations in an intrinsic  

    semiconductor are ni per cm3 at 300oK. Now, if acceptor  

    impurities are introduced with a concentration of NA per cm3 

    (where NA  > ni ), then electron concentration per cm3 

     at 300oK will be 








2.  In a P+N junction diode under reverse bias, the magnitude of 
     electric field is maximum at









3. The correct full wave rectifier circuit is :
