The emitter-base junction of a transistor is …… biased while the collector-base junction is ……. biased.

$A$ change of $0.04 \ V$ takes place between the base and the emitter when an input signal is connected to the common emitter transistor amplifier. As a result,a $20 \ \mu A$ change takes place in the base current and a change of $2 \ mA$ takes place in the collector current. The input resistance and $AC$ current gain are:

For the given Common Emitter $(CE)$ transistor circuit,the base current is $I_B = 0.04 \text{ mA}$. If the current gain $\beta = 100$ and the collector-emitter voltage $V_{CE} = 12 \text{ V}$,find the value of the collector resistance $R_C$ in $\text{k}\Omega$.

In a common emitter configuration,an $N-P-N$ transistor is connected. The current gain of the transistor is $100$. If the collector current changes by $1 \ mA$,by how much will the emitter current change in $mA$?

In an experiment,the input characteristics are shown for a $CE$ configuration $n-p-n$ transistor for different output voltages. Based on the graph,which of the following is correct?

In an $NPN$ transistor,the collector current is $10\, mA$. If $90\%$ of the electrons emitted reach the collector,then:
