If $X, Y$ and $Z$ are the sizes of the emitter,base and collector of a transistor respectively,then

In the circuit shown, the value of $\beta$ of the transistor is $48$. If the base current supplied is $200 \mu A$, what is the voltage at the terminal $Y$ (in $V$)?

In a $p-n-p$ transistor working as a common base amplifier, when the current gain is $0.96$ and emitter current is $7.2 \,mA$, the base current is (in $\,mA$)

The symbol given below represents:

In a transistor amplifier, a change of $0.2 \text{ mA}$ in the base current causes a change of $5 \text{ mA}$ in the collector current. If input resistance is $2 \text{ k}\Omega$ and voltage gain is $75$, the load resistance used in the circuit is

In a common emitter transistor amplifier,the resistance of the collector is $3 \ k\Omega$. If the current amplification factor is $100$ and the base resistance is $2 \ k\Omega$,then the power gain of the transistor is:
