Question

explain the following terms a) input impedance b) gain

Answer 1

Answer:

#The input resistance is the resistance seen by the current source or voltage source which drives the circuit.

#Current Amplification Factor (γ) Theratio of change in emitter current (ΔIE) to the change in base current (ΔIB) is known as Current Amplification factorin common collector (CC)configuration. It is denoted by γ. The current gain in CC configuration is same as in CE configuration.
