Hi,   
      
   In a textbook the emitter follower is depicted as a voltage series negative   
   feedback amplifier and a current series negative feedback amplifier as well.   
   Difference between the two circuits shown is only that the one, which is a   
   current series feedback    
   amplifier uses another load resistor coupled to the emitter resistor using one   
   capacitor that is the load resistor and emitter resistor are in parallel only   
   for ac and for dc load resistor is absent. In the one, which is shown as   
   voltage series negative    
   feedback amplifier doesn't have any load coupled to emitter resistor and   
   output is taken across emitter resistor only. Does the coupling capacitor   
   changes emitter follower from a voltage series to current siries negative   
   feedback? Please clarify.   
      
   Thanks and regards,   
   Koyel
