Question

explain the operation of npn transistor in cb mode

Answer 1

Answer:

Common Base Amplifier using an NPN Transistor

Then we can see from the basic common base configuration that the input variables relate to the emitter current IE and the base-emitter voltage, VBE, while the output variables relate to the collector current IC and the collector-base voltage, VCB.
