In an $n-p-n$ transistor amplifier,the collector current is $8 \ mA$. If $80 \%$ of the electrons from the emitter reach the collector,then ($\alpha$ and $\beta$ are current ratios):

For a given transistor,if $\alpha = I_C / I_E = 0.96$,then the current gain $\beta$ is:

In the given transistor circuit,the base current is $35 \ \mu A$. If the value of $V_{BE}$ is negligible,what is the value of $R_b$ in $k\Omega$?

An unknown transistor needs to be identified as a $npn$ or $pnp$ type. $A$ multimeter,with $+ve$ and $-ve$ terminals,is used to measure resistance between different terminals of the transistor. If terminal $2$ is the base of the transistor,then which of the following is correct for a $pnp$ transistor?

If $ \alpha $-current gain of a transistor is $ 0.98 $,what is the value of $ \beta $-current gain of the transistor?

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