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

In a common emitter transistor amplifier circuit,the current gain $\alpha = 0.8$. If the base current changes by $3 \mu A$,then the collector current changes by: (in $\mu A$)

In an $n-p-n$ transistor, $95 \%$ of emitted electrons reach the collector. If the base current is $2 \text{ mA}$, then the collector current is (in $\text{ mA}$)

Three circuit connections of a $PNP$ transistor are given below. Which of the following represents the Common-Emitter configuration?

The dc common emitter current gain of an $n-p-n$ transistor is $50$. The potential difference applied across the collector and emitter of a transistor used in $CE$ configuration is $V_{CE} = 2 \ V$. If the collector resistance $R_{C} = 4 \ k\Omega$,the base current $(I_{B})$ and the collector current $(I_{C})$ are:

In the study of a transistor as an amplifier,the ratio of collector current to emitter current is $0.98$. Then,the ratio of collector current to base current will be:
