An `NPN`-transistor circuit is arranged as shown in figure. It is

A

A common base amplifier circuit

B

A common emitter amplifier circuit

C

A common collector amplifier circuit

D

Neither of the above

Text Solution

Verified by Experts

The correct Answer is:
B
Because emitter `(N)` is common to both, base `(P)` and collector `(N)`.
