For a transistor,if the emitter current $I_E = 25 \, mA$ and the base current $I_B = 1 \, mA$,what is the ratio of the collector current $I_C$ to the emitter current $I_E$?

In a transistor,if the collector current is $98 \%$ of emitter current,then the ratio of the base and collector currents is

In a $P-N-P$ transistor,the emitter has ....... as majority carriers and the base has ....... as majority carriers.

The transistors provide good power amplification when they are used in

$A$ transistor is operated in $CE$ configuration at $V_{CC} = 2 \ V$ such that a change in base current from $100 \ \mu A$ to $200 \ \mu A$ produces a change in the collector current from $9 \ mA$ to $16.5 \ mA$. The value of current gain,$\beta$ is .........

In a common emitter transistor amplifier, $AC$ current gain is $65$, the load resistance is $5400 \text{ }\Omega$ and input resistance of the transistor is $450 \text{ }\Omega$. The voltage gain is
