In a $CE$ amplifier,the input $ac$ signal to be amplified is applied across

The voltage gain and current gain of a transistor amplifier in common emitter configuration are respectively $150$ and $50$. If the resistance in the base circuit is $850 \Omega$, then the resistance in the collector circuit is: (in $\Omega$)

For a given transistor,if $\alpha = 0.95$,find the common emitter current gain $\beta$.

In the following transistor circuit,$R_i$ is the input resistance and $R_0$ is the output resistance. The approximate voltage gain for the circuit is:

The current gain for a common emitter amplifier is $69$. If the emitter current is $7 \ mA$,the base current is......$mA$

In a common emitter transistor amplifier,the output voltage and input voltage have a phase difference of
