AC Input Resistance in Common Base Configuration

Ratio of change in emitter base  voltage  (?VEB)  to  the  resulting  change  in  emitter  current  (?IE)  is  called input resistance, i.e., at constant VCB

Value  of  input  resistance  Ri in  CB  configuration  is  very  low.   Its  value  further decreases  with  increase  in  collector-base  voltage  VCB. Typical  value  of  input resistance varies from a few ohms to 100 ohms.
