Question
A transistor is used common emitter mode as an amplifier, then
Options
A.the base emitter junction is forward biased
B.the base emitter junctionis reversed biased
C.the input signal is connected in series with the voltage applied to bias the base emitter junction
D.the input signal is connected in series with the voltage applied to bias the base collector junction
Solution
The circuit of a common emitter amplifier is as shown below
This has been shown an n-p-n transistor. Therefore, base emitter are forward biased and input signal is connected between base and emitter.
