In the study of a transistor as an amplifier,the ratio of collector current to emitter current is $0.98$. Then,the ratio of collector current to base current will be:

In a transistor, the base current is $10 \mu A$ and the emitter current is $1 \text{ mA}$. Then, the collector current is: (in $\mu A$)

In a $PNP$ transistor working as a common-base amplifier,current gain is $0.96$ and emitter current is $7.2 \, mA$. The base current is.....$mA$

In a $p-n-p$ transistor,

In a transistor,the forward bias is always kept smaller than the reverse bias. The correct reason is:

$A$ common emitter amplifier circuit,built using an $npn$ transistor,is shown in the figure. Its $dc$ current gain is $250$,$R_C = 1\,k\Omega$ and $V_{CC} = 10\,V$. What is the minimum base current for $V_{CE}$ to reach saturation? (in $\mu A$)
