Question

Why there is no collector resistance in common collector confriguaton

Answer 1

hey here is ur ans

Although the common collector amplifier is not very good at being a voltage amplifier, because as we have seen, its small signal voltage gain is approximately equal to one (AV ≅ 1), it does however make a very good voltage buffer circuit due to its high input (ZIN) and low output (ZOUT) impedances, providing isolation .
