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

For a transistor,the parameter $\beta = 99$. The value of the parameter $\alpha$ is

In a $p-n-p$ transistor, the collector current is

In an $NPN$ transistor,the collector current is $20 \, mA$. If $90\%$ of the electrons emitted reach the collector,then:

In the following common emitter circuit,$\beta=100$ and $V_{CE}=7 \text{ V}$. If $V_{BE}$ is negligible,then the base current is (in $\text{ mA}$)

Assertion : In a common emitter transistor amplifier,the input current is much less than the output current.
Reason : The common emitter transistor amplifier has very high input impedance.
