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

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

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?

An $N-P-N$ transistor conducts when:

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
